[vortex-bug] 3c905CX-TXM - One machine now works, one machine doesn't

[Garnet Chaney]

Bogdan,

I feel really silly. A new cable fixed the problem!  I now remember why I
accidentally took a bad cable with me when
I installed the machine.  Thanks for the hint.

They are really very close...

This is a bit strange. Usually, the C cards fail to have a correct
checksum; are you sure that this card (the non-working one) hasn't been
subject to the DOS 3Com config utility or something similar ? This might
influence the media selection as well.

Not really... If it's not firmly inserted in the slot, you would get
garbage out of it, while here we have coherent data.

Try switching the cables too...
