You didn't bother to mention even what bus your NICs work with, much less what models and makes, so you leave us guessing, but...
1) IRQ. If ISA cards going into a PCI machine, you need to make sure the IRQs used by your NICs need to be left open for the ISA bus in the BIOS. 2) *SOME* IBMs have very weird ISA bus timing (I think). I have had horrible problems getting any ISA NICs to work in some 486 based systems -- I believe I finally got an SMC8216 to work when a Microdyne or Eagle NE2000Plus wouldn't. This was under DOS, even -- similar results more recently with 3c509Bs -- the computer actually seemed to scramble the cards settings, rendering them unusable. Can't say if this problem extends to the Pentium class IBMs or not. 3) Shared memory (used on very few NICs) and something in the upper memory area (caching, shadowing, etc.) conflicting with the NICs.
