I see two 3c905Cs and two 3C905s.  Two different chipsets.  I don't
like that much, but it's a personal preference.

Regardless of your success in the past with 3com NICs, I would suggest
using something... ANYTHING... else.  3C90x's have been the bane of my
existence ever since they came out in the late 90s.  If there is an S3
video chipset on that motherboard, it's a lost cause.
