Two NICs in one machine - how?

Rumor has it that Russ Blakeman may have mentioned these words:

Curious if any ethernet experts are out there - I finally got my PS/2
9595-OPT server out of storage and built with WinNT4.0 and originally
wanted to put two NICs in - one is a 3Com 3C523 with AUI/Coax and the other
is a 3C529TP with AUI/RJ45 - both ethernet though. NT finds thema nd seems
to agree with them and I am able to give each a TCP/IP address but the
network never comes up. If I pull the 523 (or even the 529) it does.
Where's the conflict coming from? What's the easiest way to correct this?
I've had token ring and ethernet in at the same time int he past fine but
the problem seems to be due to the same type of network topology being
duplicated.

As they're both 3Com nic's my guess would be is that they're trying to grab
the same IRQ (and/or DMA if they use DMA) and there's IRQ conficts with
both of them in the machine.

The only thing I can think of is if you have some DOS-based 3Com NIC setup
software, boot the box with a dos boot disk with 1 of the NICs in the
machine, and configure the card to use a different IRQ (like, say, IRQ 5 if
you only have one printer port) then shutdown, insert the 2nd card & see if
it boots OK.

Dunno if this'll help, but I hope it does!
