The following lists many cards in alphabetical order by vendor name and then product identifier. Beside each product ID, you will see either `Supported', `Semi-Supported' or `Not Supported'.
Supported means that a driver for that card exists, and many people are happily using it and it seems quite reliable.
Semi-Supported means that a driver exists, but at least one
of the following descriptions is true:
(1) The driver and/or hardware are buggy, which may cause poor
performance, failing connections or even crashes.
(2) The card is fairly uncommon, and hence the driver has
seen very little use/testing and the driver author has had
very little feedback. Obviously (2) is preferable to (1), and
the individual description of the card/driver should make it
clear which one holds true. In either case, you will probably have
to answer `Y' when asked ``Prompt for development and/or
incomplete code/drivers?'' when running make config
.
For the older v1.2 kernels, the option was known
as CONFIG_NET_ALPHA
. It was changed to avoid confusion
with the Alpha-AXP line of processors made by Digital,
and to encompass all experimental drivers, not just net drivers.
Not Supported means there is not a driver currently available for that card. This could be due to a lack of interest in hardware that is rare/uncommon, or because the vendors won't release the hardware documentation required to write a driver.
Note that the difference between `Supported' and `Semi-Supported' is rather subjective, and is based on user feedback observed in newsgroup postings and mailing list messages. (After all, it is impossible for one person to test all drivers with all cards for each kernel version!!!) So be warned that you may find a card listed as semi-supported works perfectly for you (which is great), or that a card listed as supported gives you no end of troubles and problems (which is not so great).
If you are not sure what your card is, but you think it is a 3Com card, you can probably figure it out from the assembly number. 3Com has a document `Identifying 3Com Adapters By Assembly Number' (ref 24500002) that would most likely clear things up. See Technical Information from 3Com for info on how to get documents from 3Com.
Also note that 3Com has a FTP site with various goodies:

Too brain-damaged to use. Available surplus from many places. Avoid it like the plague. Again, do not purchase this card, even as a joke. It's performance is horrible, and it breaks in many ways.
Cameron L. Spitzer of 3Com said: ``I'm speaking only for myself here, of course, but I believe 3Com advises against installing a 3C501 in a new system, mostly for the same reasons Donald has discussed. You probably won't be happy with the 3C501 in your Linux box. The data sheet is marked `(obsolete)' on 3Com's Developers' Order Form, and the board is not part of 3Com's program for sending free Technical Reference Manuals to people who need them. The decade-old things are nearly indestructible, but that's about all they've got going for them any more.''
For those not yet convinced, the 3c501 can only do one thing at a time -- while you are removing one packet from the single-packet buffer it cannot receive another packet, nor can it receive a packet while loading a transmit packet. This was fine for a network between two 8088-based computers where processing each packet and replying took 10's of msecs, but modern networks send back-to-back packets for almost every transaction.
AutoIRQ works, DMA isn't used, the autoprobe only
looks at 0x280
and 0x300
, and the debug level is set
with the third boot-time argument.
Once again, the use of a 3c501 is strongly discouraged! Even more so with a IP multicast kernel, as you will grind to a halt while listening to all multicast packets. See the comments at the top of the source code for more details.

If you have a 3c503/16 you may be interested to know that as of 1.3.37 the driver has the facility to use the full 16kB RAM on your card. Previous versions treated the 16bit cards as 8bit cards, and only used half of the available RAM. This update also detects the newer 3Com prefix found on newly manufactured cards mentioned below.
Recently made 3c503/16 cards have a new base hardware address because 3Com ran out of numbers (they made too many cards!) The cards used to start with 02 60 8C and the newer ones use 00 20 AF. Up to 1.3.37, the driver will only check for the old address, and skip over the newer cards. You can upgrade to a kernel newer than 1.3.37, or change the numbers in 3c503.c for older kernels.
These shared-memory ethercards also have a programmed I/O mode that doesn't use the 8390 facilities (their engineers found too many bugs!) It should be about the same speed as the same bus width WD80x3, but it is actually a bit slower. The 3c503 does not have ``EEPROM setup'', so a diagnostic/setup program isn't needed before running the card with Linux. The shared memory address of the 3c503 is set using jumpers that are shared with the boot PROM address. This is confusing to people familiar with other ISA cards, where you always leave the jumper set to ``disable'' unless you have a boot PROM.
The Linux 3c503 driver can also work with the 3c503 in programmed-I/O mode, but this is slower and less reliable than shared memory mode. Also, programmed-I/O mode is not as well tested when updating the drivers. You still shouldn't use the programmed-I/O mode though, unless you need it for MS-DOS compatibility.
The 3c503's IRQ line is set in software, with no hints from an EEPROM. Unlike the MS-DOS drivers, the Linux driver has capability to autoIRQ: it uses the first available IRQ line in {5,2/9,3,4}, selected each time the card is ifconfig'ed. (Older driver versions selected the IRQ at boot time.) The ioctl() call in `ifconfig' will return EAGAIN if no IRQ line is available at that time.
Some common problems that people have with the 503 are discussed in Problems with....
If you intend on using this driver as a loadable module you should probably see Using the Ethernet Drivers as Modules and also 8390 Based Cards as Modules for module specific information.

This is a driver that was written by Craig Southeren
geoffw@extro.ucc.su.oz.au
. These cards also
use the i82586 chip.
There are not that many of these cards about.
It is included in the standard kernel, but it is classed as
an alpha driver. See
Alpha Drivers
for important information on using alpha-test ethernet drivers
with Linux.
There is also the file
/usr/src/linux/drivers/net/README.3c505
that you should read if you are going to use one of these cards.
It contains various options that you can enable/disable.

This card uses one of the Intel chips, and the development of the driver is closely related to the development of the Intel Ether Express driver. The driver is included in the standard kernel release, but as an alpha driver.

This card is fairly inexpensive and has good performance for a non-bus-master design. The drawbacks are that the original 3c509 requires very low interrupt latency. The 3c509B shouldn't suffer from the same problem, due to having a larger buffer. (See below.) These cards use PIO transfers, similar to a ne2000 card, and so a shared memory card such as a wd8013 will be more efficient in comparison.
The original 3c509 has a small packet buffer
(4kB total, 2kB Rx, 2kB Tx), causing the driver to
occasionally drop a packet if interrupts are masked for
too long. To minimize this problem, you can try unmasking
interrupts during IDE disk transfers (see hdparm(8)
) and/or
increasing your ISA bus speed so IDE transfers finish sooner.
The newer model 3c509B has 8kB on board, and the buffer can be split 4/4, 5/3 or 6/2 for Rx/Tx. This setting is changed with the DOS configuration utility, and is stored on the EEPROM. This should alleviate the above problem with the original 3c509. At this point in time, the Linux driver is not aware of this, and treats the 3c509B as an older 3c509.
3c509B users should use the supplied DOS
utility to disable the plug and play support, and
to set the output media to what they require. The linux
driver currently does not support the Autodetect
media setting, so you have to select 10Base-T or
10Base-2 or AUI.
With regards to the media detection features, Cameron said:
``Autoselect is a feature of the commercial drivers for 3C509(B).
AFAIK nobody ever claimed the Linux driver attempts it.
When drivers/net/3c509.c recognizes my 3C509B at boot time, it says:
eth0: 3c509 at 0x300 tag 1, 10baseT port, ...
revealing that the card is configured for 10BASE-T. It finds that out
by reading the little EEPROM, which IMHO is the Right Way To Do It.''
As for the plug-and-pray stuff, Cameron adds:
``The 3C509B has 3Com's relocatable I/O port scheme,
and Microsoft
It was a marketing decision to turn PnP on as a factory default setting. If it caused you a hassle, or not, please take the time to say so when you mail in your warranty card. The more info they have, the better decisions they can make. Also, check with your motherboard supplier to see if you need a BIOS upgrade.''
It has been reported that you have to do a hard reset after doing the `3C5X9CFG /PNPRST' for the change to take effect.
Some people ask about the ``Server or Workstation'' and ``Highest Modem Speed'' settings presented in the DOS configuration utility. Donald writes ``These are only hints to the drivers, and the Linux driver does not use these parameters: it always optimizes for high throughput rather than low latency (`Server'). Low latency was critically important for old, non-windowed, IPX throughput. To reduce the latency the MS-DOS driver for the 3c509 disables interrupts for some operations, blocking serial port interrupts. Thus the need for the `modem speed' setting. The Linux driver avoids the need to disable interrupts for long periods by operating only on whole packets e.g. by not starting to transmit a packet until it is completely transferred to the card.''
Note that the ISA card detection uses a different method
than most cards. Basically, you ask the cards to respond
by sending data to an ID_PORT (port 0x100
).
This detection method means that
a particular card will always get detected first
in a multiple ISA 3c509 configuration.
The card with the lowest hardware ethernet address
will always end up being eth0
. This shouldn't matter
to anyone, except for those people who want to assign
a 6 byte hardware address to a particular interface.
If you have multiple 3c509 cards, it is best to append
ether=0,0,ethN
commands without the i/o port specified
(i.e. use i/o=zero) and allow the probe to sort out which
card is first, otherwise it may not detect all your cards.

This MCA bus card uses the i82586, and now that people are
actually running Linux on MCA machines, people have tried
to recycle parts of the 3c507 driver into a
driver for this card. More details can be found on the
MCA-Linux page at http://glycerine.cetmm.uni.edu/mca/
Status -- Not Supported
Yes, another MCA card. No, not too much interest in it. Better chances with the 3c529 if you are stuck with MCA.
Status -- Semi-Supported
This card actually uses the same chipset as the 3c509. Donald actually put hooks into the 3c509 driver to check for MCA cards after probing for EISA cards, and before probing for ISA cards. But it hasn't evolved much further than that. Donald writes:
``I don't have access to a MCA machine (nor do I fully understand
the probing code) so I never wrote the mca_adaptor_select_mode()
or mca_adaptor_id()
routines. If you can find a way to get the
adaptor I/O address that assigned at boot time, you can just
hard-wire that in place of the commented-out probe. Be sure to
keep the code that reads the IRQ, if_port, and ethernet address.''
Darrell Frappier (aa822@detroit.freenet.org) reports that you can get the i/o address from running the PS/2 reference diskette, and once you put that directly into the driver, it does actually work.

This PCMCIA card is the combination of a 3c589B ethernet card with a modem. The modem appears as a standard modem to the end user. The only difficulty is getting the two separate linux drivers to share one interrupt. There are a couple of new registers and some hardware interrupt sharing support. You need to use a v2.0 or newer kernel that has the support for interrupt sharing.
As a side note, the modem part of the card has been reported to be not well documented for the end user (the manual just says `supports the AT command set') and it may not connect as well as other name brand modems. The recommendation is to buy a 3c589B instead, and then get a PCMCIA modem card from a company that specializes in modems.
Thanks again to Cameron for getting a sample unit and documentation sent off to David Hinds. Look for support in David's PCMCIA package release.

The EISA version of the 509. The current EISA version uses the same 16 bit wide chip rather than a 32 bit interface, so the performance increase isn't stunning. The EISA probe code was added to 3c509.c for 0.99pl14. We would be interested in hearing progress reports from any 3c579 users. (Read the above 3c509 section for info on the driver.)
Cameron Spitzer writes: ``The 3C579 (Etherlink III EISA) should be configured as an EISA card. The IO Base Address (window 0 register 6 bits 4:0) should be 1f, which selects EISA addressing mode. Logic outside the ASIC decodes the IO address s000, where s is the slot number. I don't think it was documented real well. Except for its IO Base Address, the '579 should behave EXACTLY like the'509 (EL3 ISA), and if it doesn't, I want to hear about it (at my work address).''

Many people have been using this PCMCIA card for quite some time now. Note that support for it is not (at present) included in the default kernel source tree. You will also need a supported PCMCIA controller chipset. There are drivers available on Donald's ftp site:

Or for those that are net-surfing you can try:
You will still need a PCMCIA socket enabler as well.

These ``Vortex'' cards are for PCI bus machines, with the '590 being 10Mbps and the '595 being 3Com's 100Mbs offering. Also note that you can run the '595 as a '590 (i.e. in a 10Mbps mode). The driver is included in the v2.0 kernel source, but is also continually being updated. If you have problems with the driver in the v2.0 kernel, you can get an updated driver from the following URL:
Note that there are two different 3c590 cards out there, early models that had 32kB of on-board memory, and later models that only have 8kB (eeccch!) of memory. Chances are you won't be able to buy a new 3c59x for much longer, as it is being replaced with the 3c90x card. If you are buying a used one off somebody, try and get the 32kB version. The 3c595 cards have 64kB, as you can't get away with only 8kB RAM at 100Mbps!
A thanks to Cameron Spitzer and Terry Murphy of 3Com for sending cards and documentation to Donald so he could write the driver.

These are the EISA versions of the 3c59x series of cards. The 3c592/3c597 (aka Demon) should work with the vortex driver discussed above.
Status -- Supported
These cards (aka `Boomerang', aka EtherLink III XL) have been recently released to take over the place of the 3c590/3c595 cards. Cameron Spitzer of 3Com writes that the ``3C900 has a scatter gather bus master controlled by a descriptor ring in main memory. Aside from that, it's a lot like 3C590.''
You may still be able to get a couple of these cards at a reduced price through one of 3Com's evaluation deals, if you are quick.
To use this card with v2.0 kernels, you must obtain the
updated 3c59x.c
driver from Donald's site at:
This updated 3c59x driver allows you to use the 3c900 in a 3c59x compatible mode, and has been reported to be quite stable. Note that this updated driver may be snuck into the v2.0 source tree at a later date.)
On the same WWW page, you will also find the
experimental boomerang.c
driver which uses some of
the enhancements of the 3c900 over that which is available
on the 3c59x cards. Since this is a new/experimental driver,
you may be better off in using the updated 3c59x.c
if system stability is a primary concern.

Don't let the name fool you. This is still supposed to be a NE2000 compatible card. The MPX is supposed to stand for MultiPacket Accelerator, which, according to Accton, increases throughput substantially. But if you are already sending back-to-back packets, how can you get any faster...

This is another implementation of the DEC 21040 PCI chip. Someone once mentioned that they had a bit of trouble with one of the above cards and the drivers at that point in time, so as with all purchases, you should try and make sure you can return it if it doesn't work for you.
See DEC 21040 for more information on these cards, and the present driver situation.

This will probably be changed for v2.1 kernels.
The Allied Telesis AT1700 series ethercards are based on the Fujitsu MB86965. This chip uses a programmed I/O interface, and a pair of fixed-size transmit buffers. This allows small groups of packets to be sent back-to-back, with a short pause while switching buffers.
A unique feature is the ability to drive 150ohm STP (Shielded Twisted Pair) cable commonly installed for Token Ring, in addition to 10baseT 100ohm UTP (unshielded twisted pair). A fibre optic version of the card (AT1700FT) exists as well.
The Fujitsu chip used on the AT1700 has a design flaw: it can only be fully reset by doing a power cycle of the machine. Pressing the reset button doesn't reset the bus interface. This wouldn't be so bad, except that it can only be reliably detected when it has been freshly reset. The solution/work-around is to power-cycle the machine if the kernel has a problem detecting the AT1700.
Some production runs of the AT1700 had another problem: they are permanently wired to DMA channel 5. This is undocumented, there are no jumpers to disable the "feature", and no driver dares use the DMA capability because of compatibility problems. No device driver will be written using DMA if installing a second card into the machine breaks both, and the only way to disable the DMA is with a knife.
Status -- Supported
This is the PCI version of the AT1500, and it doesn't suffer from the problems that the Boca 79c970 PCI card does. Allied Telsyn was still `beta testing' the card in early/mid 1995, so it may not have spread to various retailers yet (but it doesn't hurt to ask.)

There really is no AMD ethernet card. You are probably reading this because the only markings you could find on your card said AMD and the above number. The 7990 is the original `LANCE' chip, but most stuff (including this document) refer to all these similar chips as `LANCE' chips. (...incorrectly, I might add.)
These above numbers refer to chips from AMD that are the heart of many ethernet cards. For example, the Allied Telesis AT1500 (see AT1500) the NE1500/2100 (see NE1500) and the Boca-VLB/PCI cards (see Boca-VLB/PCI)
The 79C960 (a.k.a. PCnet-ISA) contains enhancements and bug fixes over the original 7990 LANCE design.
One common problem people have is the `busmaster arbitration failure' message. This is printed out when the LANCE driver can't get access to the bus after a reasonable amount of time has elapsed (50us). This usually indicates that the motherboard implementation of bus-mastering DMA is broken, or some other device is hogging the bus, or there is a DMA channel conflict. If your BIOS setup has the `GAT option' (for Guaranteed Access Time) then try toggling/altering that setting to see if it helps.
Chances are that the existing LANCE driver will work with all AMD LANCE based cards. (except perhaps some of the original 7990 designs with shared memory.) This driver should also work with NE1500 and NE2100 clones.
For the ISA bus master mode all structures used directly by the LANCE, the initialization block, Rx and Tx rings, and data buffers, must be accessible from the ISA bus, i.e. in the lower 16M of real memory. If more than 16MB of memory is installed, low-memory `bounce-buffers' are used when needed.
The DMA channel can be set with the low bits of the otherwise-unused dev->mem_start value (a.k.a. PARAM_1). (see PARAM_1) If unset it is probed for by enabling each free DMA channel in turn and checking if initialization succeeds.
The HP-J2405A board is an exception: with this board it's easy to read the EEPROM-set values for the IRQ, and DMA.

This is the PCnet-ISA+ -- an enhanced version of the 79C960. It has support for jumper-less configuration and Plug and Play. Also see the info in the above section.
Dave Platt writes: ``The Lance driver may report recent versions of this chip as `PCnet (unknown)', as the ID number in newer '961s seems to have been revised (it's now 0x2261 rather than 0x2260). This misidentification shouldn't prevent the driver from working with it, though. I've been told of a problem with the '961 - it will work correctly the first time you boot Linux after a hard reset, but will not work correctly after a soft reboot. From the data sheet, it looks as if the '961 disables itself upon reset, and won't "talk" again until the motherboard BIOS goes through the Plug+Play probe-and-enable sequence, and this might not be happening during a soft reboot. I do not yet know of a good workaround for this problem.''

This is the PCnet-32 -- a 32 bit bus-master version of the original LANCE chip for VL-bus and local bus systems. Minor cleanups were added to the original lance driver around v1.1.50 to support these 32 bit versions of the LANCE chip. The main problem was that the current versions of the '965 and '970 chips have a minor bug. They clear the Rx buffer length field in the Rx ring when they are explicitly documented not to. Again, see the above info.
Status -- Supported
This is the PCnet-PCI -- similar to the PCnet-32, but designed for PCI bus based systems. Again, see the above info. Donald has modified the LANCE driver to use the PCI BIOS structure that was introduced by Drew Eckhardt for the PCI-NCR SCSI driver. This means that you need to build a kernel with PCI BIOS support enabled.

This on board ethernet uses an i82596 bus-master chip.
It can only be at i/o address 0x300
. The author of this
driver is Mark Evans. By looking at the driver source,
it appears that the IRQ is hardwired to 10.
Earlier versions of the driver had a tendency to think
that anything living at 0x300
was an apricot NIC.
Since then the hardware address is checked to avoid these
false detections.

With the very low cost and better performance of ethernet, chances are that most places will be giving away their Arcnet hardware for free, resulting in a lot of home systems with Arcnet.
An advantage of Arcnet is that all of the cards have identical interfaces, so one driver will work for everyone. It also has built in error handling so that it supposedly never loses a packet. (Great for UDP traffic!)
Avery Pennarun's arcnet driver has been in the default kernel sources since 1.1.80. The arcnet driver uses `arc0' as its name instead of the usual `eth0' for ethernet devices. Bug reports and success stories can be mailed to:
apenwarr@foxnet.net
There are information files contained in the standard kernel for setting jumpers and general hints.
Supposedly the driver also works with the 100Mbs ARCnet cards as well!
Note that AT&T's StarLAN is an orphaned technology, like SynOptics LattisNet, and can't be used in a standard 10Base-T environment, without a hub that `speaks' both.

This is a generic, low-cost OEM pocket adaptor being sold by AT-Lan-Tec, and (likely) a number of other suppliers. A driver for it is included in the standard kernel. Note that there is substantial information contained in the driver source file `atp.c'. BTW, the adaptor (AEP-100L) has both 10baseT and BNC connections! You can reach AT-Lan-Tec at 1-301-948-7070. Ask for the model that works with Linux, or ask for tech support. Apparently there are various clones of this adaptor being sold here and there throughout Europe as well.
The adaptor is `normal size' for the product class, about 57mm wide, 22mm high tapering to 15mm high at the DB25 connector, and 105mm long (120mm including the BNC socket). It's switchable between the RJ45 and BNC jacks with a small slide switch positioned between the two: a very intuitive design.
Donald performed some power draw measurements, and determined that the average current draw was only about 100mA @ 5V. This power draw is low enough that you could buy or build a cable to take the 5V directly from the keyboard/mouse port available on many laptops. (Bonus points here for using a standardized power connector instead of a proprietary one.)
Note that the device name that you pass to ifconfig
is not eth0
but atp0
for this device.

Donald did a comparitive test with the above Boca PCI card and a similar Allied Telsyn PCnet/PCI implementation, which showed that the problem lies in Boca's implementation of the PCnet/PCI chip. These test results can be accessed on Don's www server.
Also, Dave Platt has compared the recommended implementation given on the AMD data sheet with the Boca implementation, and has determined that Boca has left out a substantial number of important filtering capacitors. At the risk of being verbose, here is a quote from Dave, which will allow you to assess if the problem has been addressed yet, given a card for visual inspection.
``I just reviewed Appendix B in the 79c970 data sheet. It recommends a _minimum_ of 8 high-frequency bypassing caps (.1 uF multilayer ceramic) around the chip, to keep ground and power bounce from causing unreliable operation. Looking at the card I have here, I see a total of 5 such caps on the entire card - only a couple of them are close enough to the chip to do a decent job of high-frequency bypassing.
If you hold the card with chips facing up, and the PCI pins pointed towards you, the lower-left corner of the '970 has the positioning dimple. The upper-left corner of the chip is the `analog corner', where the analog power and ground pins are. Appendix B calls these `the most cricical pins in the layout of a PCnet-PCI card'. There are 4 analog power pins, and 2 analog ground pins... all of them are supposed to be connected, and properly bypassed.
On the left side of the chip, the uppermost pin is AVSS1 (analog ground 1). On the top edge, the fourth pin from the left is AVDD3 (analog power 3). The Appendix specifically recommends having a .1 uF bypass cap tied directly to these two pins (not going through the common ground plane). On the card I have, there is no such cap - the nearest bypass cap is about half-an-inch away over by the crystal, and is tied to the ground plane.
The Appendix also specifically recommends `low-frequency bulk capacitors' (by which I assume that they mean multi-uF tantalum or aluminum electrolytics) as well as high-frequency bypass caps. I see only two bulk capacitors (one 10 uF in the AVSS2/AVDD2 filter circuit, and one 4.7 uF up above the chip which also appears to be part of a filter circuit). The Appendix recommends `at least one low-frequency bulk (e.g. 22 uF) bypass capactor... connected directly to the power and ground planes.' There is no capacitor on the board which matches this description.
It appears that Boca ignored _several_ of AMD's recommendations, regarding the number, size, placement, and wiring of the power supply bypass capacitors.''
(Thanks Dave.) Boca is offering a `warranty repair' for affected owners, which involves adding one of the missing capacitors, but it appears that this fix doesn't work 100 percent for most people, although it helps some.
If you are still thinking of buying one of these cards, then at least try and get a 7 day unconditional return policy, so that if it doesn't work properly in your system, you can return it.

If you feel like asking them why they don't want to release their low level programming info so that people can use their cards, write to support@ctron.com.

Again, there is not much one can do when the programming information is proprietary. The E2100 is a poor design. Whenever it maps its shared memory in during a packet transfer, it maps it into the whole 128K region! That means you can't safely use another interrupt-driven shared memory device in that region, including another E2100. It will work most of the time, but every once in a while it will bite you. (Yes, this problem can be avoided by turning off interrupts while transferring packets, but that will almost certainly lose clock ticks.) Also, if you mis-program the board, or halt the machine at just the wrong moment, even the reset button won't bring it back. You will have to turn it off and leave it off for about 30 seconds.
Media selection is automatic, but you can override this
with the low bits of the dev->mem_end parameter.
See
PARAM_2. Module users
can specify an xcvr=N
value on the insmod
command line to do the same.
Also, don't confuse the E2100 for a NE2100 clone. The E2100 is a shared memory NatSemi DP8390 design, roughly similar to a brain-damaged WD8013, whereas the NE2100 (and NE1500) use a bus-mastering AMD LANCE design.
There is an E2100 driver included in the standard kernel. However, seeing as programming info isn't available, don't expect bug-fixes. Don't use one unless you are already stuck with the card.
If you intend on using this driver as a loadable module you should probably see Using the Ethernet Drivers as Modules and also 8390 Based Cards as Modules for module specific information.

Compaq aren't really in the business of making ethernet cards, but a lot of their systems have embedded ethernet controllers on the motherboard.
Machines such as the XL series have an AMD 79c97x PCI chip on the mainboard that can be used with the standard LANCE driver. But before you can use it, you have to do some trickery to get the PCI BIOS to a place where Linux can see it. Frank Maas was kind enough to provide the details:
`` The problem with this Compaq machine however is that the PCI directory is loaded in high memory, at a spot where the Linux kernel can't (won't) reach. Result: the card is never detected nor is it usable (sideline: the mouse won't work either) The workaround (as described thoroughly in http://www-c724.uibk.ac.at/XL/) is to load MS-DOS, launch a little driver Compaq wrote and then load the Linux kernel using LOADLIN. Ok, I'll give you time to say `yuck, yuck', but for now this is the only working solution I know of. The little driver simply moves the PCI directory to a place where it is normally stored (and where Linux can find it).''

``Since the DE-620 driver tries to sqeeze the last microsecond

As of linux v1.0, there is a driver included as standard
for these cards. It was written by David C. Davies.
There is documentation included in the source file
`depca.c', which includes info on how to use more than
one of these cards in a machine. Note that the DE422 is
an EISA card. These cards are all based on the AMD LANCE chip.
See
AMD LANCE for more info.
A maximum of two of the ISA cards can be used, because they
can only be set for 0x300
and 0x200
base I/O address.
If you are intending to do this, please read the notes in
the driver source file depca.c
in the standard kernel
source tree.
This driver will also work on Alpha CPU based machines, and there are various ioctl()s that the user can play with.
Status -- Supported
Included into kernels v1.1.62 and above is this driver,
also by David C. Davies of DEC. These cards use a proprietary
chip from DEC, as opposed to the LANCE chip used in the
earlier cards like the DE200. These cards support both shared
memory or programmed I/O, although you take about a 50%performance hit if you use PIO mode. The shared memory size can
be set to 2kB, 32kB or 64kB, but only 2 and 32 have been tested
with this driver. David says that the performance is virtually
identical between the 2kB and 32kB mode. There is more information
(including using the driver as a loadable module) at the top
of the driver file ewrk3.c
and also in README.ewrk3
.
Both of these files come with the standard kernel distribution.
The standard driver has a number of interesting ioctl() calls that can be used to get or clear packet statistics, read/write the EEPROM, change the hardware address, and the like. Hackers can see the source code for more info on that one.
David has also written a configuration utility for this
card (along the lines of the DOS program NICSETUP.EXE
)
along with other tools. These can be found on
sunsite.unc.edu
in the directory
/pub/Linux/system/Network/management

These cards are based on the 21040 chip mentioned below. Included into kernels v1.1.86 and above is this driver, also by David C. Davies of DEC. It sure is nice to have support from someone on the inside ;-) The DE500 uses the newer 21140 chip to provide 10/100Mbs ethernet connections. Have a read of the 21040 section below for extra info.
Note that as of 1.1.91, David has added a compile time option that
will allow non-DEC cards to work with
this driver. Have a look at README.de4x5
for details.
All the Digital cards will autoprobe for their media (except, temporarily, the DE500 due to a patent issue).

The DEC 21040 is a bus-mastering single chip ethernet solution from Digital, similar to AMD's PCnet chip. The 21040 is specifically designed for the PCI bus architecture. SMC's new EtherPower PCI card uses this chip.
You have a choice of two drivers for cards based on this chip. There is the DE425 driver discussed above, and the generic 21040 driver that Donald has written.
The updated 21041 chip is also found in place of the 21040
on newly produced SMC EtherPower cards.
The 21140 is for supporting 100Base-? and
works with the Linux drivers for the 21040 chip.
To use David's de4x5
driver with non-DEC cards, have a
look at README.de4x5

Donald has used SMC EtherPower-10/100 cards to develop the `tulip' driver. Note that the driver that is in the standard kernel tree at the moment is not the most up to date version. If you intend on using this driver, you should get the newest version from Donald's ftp/WWW site.
The above URL also contains a (non-exhaustive) list of various cards/vendors that use the 21040 chip.
Also note that the tulip driver is still considered an alpha
driver (see
Alpha Drivers) at the
moment, and should be treated as such. To use it, you
will have to edit arch/i386/config.in
and
uncomment the line for CONFIG_DEC_ELCP
support.

This is reported to be a 3c509 clone that includes the EtherWave transceiver. People have used these successfully with Linux and the present 3c509 driver. They are too expensive for general use, but are a great option for special cases.

The 272** cards use programmed I/O, similar to the NE*000 boards, but the data transfer port can be `turned off' when you aren't accessing it, avoiding problems with autoprobing drivers.

These are lower priced, and slightly faster than the 27247/27252A, but are missing some features, such as AUI, ThinLAN connectivity, and boot PROM socket.

NOTE: If you are using a kernel that is older than v1.2.9, it is strongly recommended that you upgrade to a newer version. There was an important bugfix made to the ne driver in 1.2.7, and another important bugfix made to the upper layers (dev.c) in 1.2.9. Both of these bugs can cause a ne2000 card to hang your computer.
The ne2000 is now a generic name for a bare-bones design around the NatSemi 8390 chip. They use programmed I/O rather than shared memory, leading to easier installation but slightly lower performance and a few problems. Again, the savings of using an 8 bit NE1000 over the NE2000 are only warranted if you expect light use. Some problems can arise with poor NE2000 clones. You should see Problems with..., and Poor NE2000 Clones
Some recently introduced NE2000 clones use the National Semiconductor `AT/LANTic' 83905 chip, which offers a shared memory mode similar to the wd8013 and EEPROM software configuration. The shared memory mode will offer less CPU usage (i.e. more efficient) than the programmed i/o mode.
In general it is not a good idea to put a NE2000
clone at I/O address 0x300
because nearly
every device driver probes there at boot. Some
poor NE2000 clones don't take kindly to being prodded
in the wrong areas, and will respond by locking your
machine. Also 0x320
is bad because SCSI drivers
probe into 0x330
.
Donald has written a NE2000 diagnostic program (ne2k.c) for all ne2000 cards. See Diagnostic Programs for more information.

Yes, believe it or not, people are making PCI cards based on the ten year old interface design of the ne2000. At the moment nearly all of these cards are based on the RealTek 8029 chip, and linux kernel v2.0 has support to automatically detect these cards at boot and use them.
If you have a NE2000 PCI card that is not based on
the RealTek 8029 chip, please contact the maintainer of
the NE2000 driver as listed

of your card can also be added to the driver.
Note that you have to say `Y' to the `Other ISA cards'
option when running make config
as you are actually
using the same NE2000 driver as the ISA cards use.
If you are using the driver as a module, you will have to
supply the i/o address of the card (obtained from doing
a cat /proc/pci
) when loading the module.
Note that this will not be necessary for future kernels.

These cards use the original 7990 LANCE chip from AMD and are supported using the Linux lance driver. Newer NE2100 clones use the updated PCnet/ISA chip from AMD.

currently is non-operational, so you have to supply them at
boot; e.g. ether=5,0,0xd0000,eth0
for IRQ 5 and shared

. The i/o base is automatically detected
and hence a non-zero value need not be supplied.

As of kernel 1.3.23, the generic LANCE driver had a check

Others have reported that this signature is not the same
for all NI6510EB cards however, which will cause the lance
driver to not detect your card. If this happens to you, you
can change the probe (at about line 322 in lance.c) to printk()
out what the values are for your card and then use them instead
of the 0x52, 0x44

The cards should probably be run in `high-performance' mode and not in the NI6510 compatible mode when using the lance driver.

This driver was included into the v1.1 kernels, and it was written by PJD Weichmann and SWS Bern. It appears that the SK G16 is similar to the NI6510, in that it is based on the first edition LANCE chip (the 7990). Once again, it appears as though this card won't work with the generic LANCE driver.

This driver was included into early 1.3.x kernels, and was written by Hamish Coleman. There is little information about the card included in the driver, and hence little information to be put here. If you have a question, you are probably best off e-mailing hamish@zot.apana.org.au
Please see Western Digital for information on SMC cards. (SMC bought out Western Digital's network card section quite a while ago.)
This is yet another PCI card that is based on DEC's 21040 chip.
See the section on the 21040 chip ( DEC 21040) for more information.
The ethernet part of Western Digital has been bought out by SMC. One common mistake people make is that the relatively new SMC Elite Ultra is the same as the older SMC Elite16 models -- this is not the case. They have separate drivers.

These are the 8-bit versions of the card. The
8 bit 8003 is slightly less expensive, but only
worth the savings for light use. Note that some
of the non-EEPROM cards (clones with jumpers, or
old old old wd8003 cards) have no way of reporting
the IRQ line used. In this case, auto-irq is used, and if
that fails, the driver silently assings IRQ 5.
You can get the SMC setup/driver disks from SMC's ftp site.
Note that some of the
newer SMC `SuperDisk' programs will fail to detect
the real old EEPROM-less cards. The file SMCDSK46.EXE
seems to be a good all-round choice. Also the jumper
settings for all their cards are in an ascii text file in the
aforementioned archive. The latest (greatest?) version
can be obtained from ftp.smc.com
.
As these are basically the same as their 16 bit counterparts (WD8013 / SMC Elite16), you should see the next section for more information.

Over the years the design has added more registers and an EEPROM. (The first wd8003 cards appeared about ten years ago!) Clones usually go by the `8013' name, and usually use a non-EEPROM (jumpered) design. Late model SMC cards will have the SMC 83c690 chip instead of the original Nat Semi DP8390 found on earlier cards. The shared memory design makes the cards a bit faster than PIO cards, especially with larger packets. More importantly, from the driver's point of view, it avoids a few bugs in the programmed-I/O mode of the 8390, allows safe multi-threaded access to the packet buffer, and it doesn't have a programmed-I/O data register that hangs your machine during warm-boot probes.
Non-EEPROM cards that can't just read the selected IRQ will attempt auto-irq, and if that fails, they will silently assign IRQ 10. (8 bit versions will assign IRQ 5)
Cards with a non standard amount of memory on board can have the memory size specified at boot (or at `insmod' time if using modules). The standard memory size is 8kB for an 8bit card and 16kB for a 16bit card. For example, the older WD8003EBT cards could be jumpered for 32kB memory. To make full use of that RAM, you would use something like (for i/o=0x280 and IRQ 9):
LILO: linux ether=9,0x280,0xd0000,0xd8000,eth0
Also see 8013 problems for some of the more common problems and frequently asked questions that pop up often.
If you intend on using this driver as a loadable module you should probably see Using the Ethernet Drivers as Modules and also 8390 Based Cards as Modules for module specific information.
Status -- Supported
This ethercard is based on a new chip from SMC, the 83c790, which has a few new features. While it has a mode that is similar to the older SMC ethercards, it's not entirely compatible with the old WD80*3 drivers. However, in this mode it shares most of its code with the other 8390 drivers, while operating slightly faster than a WD8013 clone.
Since part of the Ultra looks like an 8013, the Ultra probe is supposed to find an Ultra before the wd8013 probe has a chance to mistakenly identify it.
Donald mentioned that it is possible to write a separate driver for the Ultra's `Altego' mode which allows chaining transmits at the cost of inefficient use of receive buffers, but that will probably not happen.
Bus-Master SCSI host adaptor users take note: In the manual that ships with Interactive UNIX, it mentions that a bug in the SMC Ultra will cause data corruption with SCSI disks being run from an aha-154X host adaptor. This will probably bite aha-154X compatible cards, such as the BusLogic boards, and the AMI-FastDisk SCSI host adaptors as well.
SMC has acknowledged the problem occurs with
Interactive, and older Windows NT drivers. It is
a hardware conflict with early revisions of the card
that can be worked around in the driver design. The current
Ultra driver protects against this by only enabling the
shared memory during data transfers with the card. Make sure
your kernel version is at least 1.1.84, or that the driver
version reported at boot is at least smc-ultra.c:v1.12
otherwise you are vulnerable.
If you intend on using this driver as a loadable module you should probably see Using the Ethernet Drivers as Modules and also 8390 Based Cards as Modules for module specific information.

This card uses SMC's 83c795 chip and supports the Plug 'n Play specification. It also has an SMC Ultra compatible mode, which allows it to be used with the Linux Ultra driver. Be sure to set your card for this compatibility mode. See the above information for notes on the Ultra driver.
For v1.2 kernels, the card had to be configured for shared memory operation. However v2.0 kernels can use the card in shared memory or programmed i/o mode. Shared memory mode will be slightly faster, and use considerably less CPU resources as well.
Note that the EtherEZ specific checks were added to the SMC Ultra driver in 1.1.84, and hence earlier kernel versions will not detect or handle these cards correctly.

These cards are
a basic DEC 21040 implementation, i.e. one big chip
and a couple of transceivers. Donald has used one
of these cards for his development of the generic
21040 driver (aka tulip.c
). Thanks to Duke Kamstra,
once again, for supplying a card to do development on.
Some of the newer revisons of this card use the newer DEC 21041 chip, which may cause problems with older versions of the tulip driver. If you have problems, make sure you are using the latest driver release, which may not yet be included in the current kernel source tree.
See DEC 21040 for more details on using one of these cards, and the current status of the driver.

These 8 bit cards are based on the Fujitsu MB86950, which is an ancient version of the MB86965 used in the Linux at1700 driver. Russ says that you could probably hack up a driver by looking at the at1700.c code and his DOS packet driver for the Tiara card (tiara.asm). They are not very common.
Status -- Not Supported
These are 16bit i/o mapped 8390 cards, much similar to a generic NE2000 card. If you can get the specifications from SMC, then porting the NE2000 driver would probably be quite easy. They are not very common.

The SMC9000 is a VLB card based on the 91c92 chip. The 91c92 appears on a few other brand cards as well, but is fairly uncommon. Erik Stahlman (erik@vt.edu) has written this driver which is in v2.0 kernels, but not in the older v1.2 kernels. You may be able to drop the driver into a v1.2 kernel source tree with minimal difficulty.
Status -- Semi-Supported
The SMC 91c92 driver is supposed to work for cards based on this 100Base-T chip, but at the moment this is unverified.
For the longest time, Xircom wouldn't release the programming information required to write a driver, unless you signed your life away. Apparently enough linux users have pestered them for driver support (they claim to support all popular networking operating systems...) so that they have changed their policy to allow documentation to be released without having to sign a non-disclosure agreement, and apparently they will release the source code to the SCO driver as well. If you want to verify that this is the case, you can reach Xircom at 1-800-874-7875, 1-800-438-4526 or +1-818-878-7600.
However, at the moment nobody has rushed forth offering to write any drivers, so all their products are still unsupported.
Status -- Not Supported
Not to get your hopes up, but if you have one of these parallel port adaptors, you may be able to use it in the DOS emulator with the Xircom-supplied DOS drivers. You will have to allow DOSEMU access to your parallel port, and will probably have to play with SIG (DOSEMU's Silly Interrupt Generator).

The built-in Z-Note network adaptor is based on the Intel
i82593 using two DMA channels. There is an (alpha?) driver
available in the present kernel version. As with all notebook
and pocket adaptors, it is under the `Pocket and portable
adaptors' section when running make config
.
See
Programming the Intel chips
for more technical information.
Also note that the IBM ThinkPad 300 is compatible with the Z-Note.

You have a choice of two drivers for cards based on this chip. There is the DE425 driver written by David, and the generic 21040 driver that Donald has written.
Note that as of 1.1.91, David has added a compile time option that
may allow non-DEC cards (such as the Znyx cards) to work with
this driver. Have a look at README.de4x5
for details.
See DEC 21040 for more information on these cards, and the present driver situation.
There are a few other drivers that are in the linux source, that present an ethernet-like device to network programs, while not really being ethernet. These are briefly listed here for completeness.
dummy.c
- The purpose of this driver is to provide a device
to point a route through, but not to actually transmit packets.
eql.c
- Load Equalizer, enslaves multiple devices (usually
modems) and balances the Tx load across them while presenting
a single device to the network programs.
ibmtr.c
- IBM Token Ring, which is not really ethernet.
Broken-Ring requires source routing and other uglies.
loopback.c
- Loopback device, for which all packets
from you machine and destined for your own machine go.
It essentially just moves the packet off the Tx queue and
onto the Rx queue.
pi2.c
- Ottawa Amateur Radio Club PI and PI2 interface.
plip.c
- Parallel Line Internet Protocol, allows two
computers to send packets to each other over two joined
parallel ports in a point-to-point fashion.
ppp.c
- Point-to-Point Protocol (RFC1331), for the
Transmission of Multi-protocol Datagrams over a
Point-to-Point Link (again usually modems).
slip.c
- Serial Line Internet Protocol, allows two
computers to send packets to each other over two joined
serial ports (usually via modems) in a point-to-point fashion.
tunnel.c
- Provides an IP tunnel through which you can
tunnel network traffic transparently across subnets
wavelan.c
- An Ethernet-like radio transceiver
controlled by the Intel 82586 coprocessor which is used on
other ethercards such as the Intel EtherExpress.
