I have a GVC 10/100 PCMCIA ethernet adapter that DSL doesn't recognize, the pcmcia card control sees that it's a a dual speed 10/100 pc card, but ifup eth0 gives "ignoring unknown interface eht0"

Has anyone ever gotten a gvc pcmcia card running?

Thanks

Step through the problem.

First, find out if your card is supported by Linux PCMCIA card services - see the following list:

< http://pcmcia-cs.sourceforge.net/ftp/SUPPORTED.CARDS >

The two GVC cards I found in this list were supported by a driver called pcnet_cs. This is included in the DSL distribution and you can find the driver module (pcnet_cs.o) in:

/lib/modules/2.4.26/pcmcia (DSL 2.2 onwards) or
/lib/modules/2.4.31/pcmcia (DSL 2.0 and 2.1b)

If the PCMCIA cardmanager has correctly recognised the card, it will load this module. You can check this by doing an "lsmod" command before and after you insert the card. You should see the pcmcia_core, yenta_socket and ds modules already loaded as they do the low-level card management. You should hear two beeps when you insert the card and subsequently the pcnet_cs module should load.

If the module is not there, you will not be able to get anywhere unless you manually load it using "insmod pcnet_cs".

If the module has correctly loaded then you will see it included in the list from lsmod. Now do an ifconfig. You should only see the local loopback link "lo" listed.

To get eth0 loaded, do an "ifconfig eth0 up" and this will bring up your card. You can do a plain "ifconfig" to see it is there. Make sure you are connected to your LAN and then do a "pump -i eth0" to get an IP address allocated. To see that everything is working, do a "ping google.com". You should see packets being sent and received with round trip times shown.

I forgot to include that with most of the configuration commands you will have to be super-user or put a "sudo" in front of each.

This should be all you need to do. For more information, you might want to look up the Linux networking howto on the net.

Hope this helps.

Jonam

Thanks for the answer jonam... I tried what you said, however, pcnet_cs didn't load (the other 2 did).

When I try to start it manually, it gives me an error..

I managed to get 2 3com pcmcia cards, with the same result (they are both listed in the supported cards list), the 3ccfe575ct and the 3c574-tx... Yet, not working.

Trying to bring up eth0 still says ignoring unknown interface eht0...

Is it possilble that I would need the syslinux version of DSL to get this working?

Can you type the following commands and see if there are any error messages related to loading this card?

1. dmesg (or dmesg | more)
2. sudo cat /var/log/messages | more

The PCMCIA control panel should also be able to see the card if it is properly recognised. Have look at this and try and eject/ insert/ reset the card to see what happens.

I am assuming you have this on a laptop. What model of computer are you using?
