ingvar: I'm positive that the 3com 3c905b-tx cards work in Linux, and it should work in any 2.2.x kernel, I believe. I know that it at least works in the later ones. A guy at work is using one in a Linux box right now, in fact (He's using a 2.2.14 kernel, just upgraded from a 2.2.12). The corect kernel driver for this card is 3c59x.o, so make sure you got that one....there's quite a few 3com drivers in there, so it's easy to miss it.

If that still isn't getting it, you might want to check IRQ's and make sure that there isn't some kind of conflict going on. Especially in slighty older machines (slower than 300MHz), where they didn't know how to share IRQs properly, it's easy to come up with those.

In general, I would prolly suggest upgrading to a 2.2.14 kernel either way, as it does provide some important updates. If you still can't get it to work, let me know and I'll see if I can come up with anything else. (My job for the past three years as a cable modem installer involves doing a *lot* of NIC installations. ;-)
