Multiple ethernet cards

I expected that I would need to change the IRQ on one or the
other card. The 3Com card does not have any toggle switches
which can be set.
In a previous message I mentioned this problem, but didn't
mention that one of the cards was not PCI. Does anyone know
how I can change the IRQ's?
P.S. I have no DOS.
