Netflex-2 EISA drivers for Linux?

[unknown_6]

Greetings,
I have a couple of Prosignia 486's with the
upgrade CPU. I have recently retired one that
was running NT4 in an attempt to make it a
router. I have filled it with Netflex-2 EISA
network cards and attempted to install FreeBSD
and Linux without success. They both *do*
install alright.
However, I am unable to get them to discover
the Netflex cards. Does anyone have any idea
what I need to do?
Is it the tLan driver (Lance), the NIxxx,
or...? Please help, I've been at this for days
and am going absolutely crazy.

Thank you very much for all your time and
consideration in this matter.
