Unhappy 3c905c ethernet card not working with 2.6 kernel, MDK10; tried all other forums

Hi, everybody.

I've recently installed Mandrake 10 Community on my system, and have come upon a real stumper of a problem with my ethernet card. eth0 always fails to load, which makes sense because according to 3COM's web site, the driver that comes with the distrobution (3c50x) is incompatible with my card, the 3c905C-TX. I have downloaded all their drivers and scoured the internet for more, but have come to a brick wall in that I can't get them to install properly.

During the module process there are many pages of error messages and finally when I go to load the module ("insmod 3c90x.o", according to their instructions), it says it's an "invalid module format." With some of the other drivers I've tried they simply won't compile at all, though I *think* I've executed their instructions exactly. I've inserted the alias "eth0 3c90x" into the /etc/modules file, but it persists in loading the version that doesn't work, 3c50x.

Any help you can render would be immensly appreciated. Thanks!

(as root) try:

modprobe 3c90x

.. if that works, add

alias eth0 3c90x

to /etc/modprobe.conf

Hey DaneM,
I have the exact same problem with exact ethernet card. Kernel 2.6.** does not like it. I am very much a newbie, so I am still finding my way around. I was able to get the card configured properly with the 2.4.25-2mdk kernel that came with the installation. However, I, like you, would like to run the 2.6.*.*mdk kernel. It is just so very robust on my other machine.

Have you found anything that works yet. I have yet to try the possible solution above as I have just discovered this thread. I'll power down and reboot into the 2.6 kernel and give it a try. I am glad I am not the only one with this problem. Good luck.

Hi, everybody! Thanks very much for the responses. I'll give your suggestion a try, slimjim. I just got another reply from somebody in another thread, and have yet to try that. Here's the link:

I'll let you all know if I manage to get this working and post my solution!

The .o module format has been deprecated by the new module format in the 2.6 kernels (I believe its .ko). Youll have to find a 2.6 kernel module, or compile the module from sources.
