NetBSD 1.5 (GENERIC) i386
(I don't have NetBSD running at the moment). The boot floppy can't access the interface.
My ethernet controller cannot access the internet. The interface is a 3Com card built in into Dell Precision Workstation 410. Windows reports it as 

3Com 3c918 Integrated Fast Ethernet Controller
(3c905B-TX Compatible)

NetBSD (OpenBSD and FreeBSD as well) reports it as 3c905B-TX

A plug-in card 3c905B-TX works fine.

The internal interface seems to have a 0x0 revision. The plugin card is 0x30.

The problem might be a conflict too. I have two 3Com interfaces in one box. One is the built in one (the 918 3c905B-TX lookalike) and the other one is a real PCI plug-in 3c905B-TX card.
I don't know how to repeat the problem. It is repeatable on my machine every time I try it. Both interfaces work with FreeBSD and OpenBSD (I have both installed right now and working without a problem). NetBSD however can't access that interface.
