Here's how I've got one setup: (it's a 3C503TP)

These are the important ones:
Memory: DISABLE (not sure if that's best, but the DOS drivers require it)
I/O: 300 (set's your base I/O port)

Misc others: (these are all factory defaults)
Link Pulse: ON
Equal: TX
Threshhold: NORM
Impedance: 100
Xmit Level: NORM
DC Sig: OFF

Note that the IRQ is set by software, as well as the EXTERNAL/ONBOARD
transciever selection. In Linux' case, check the net Makefile; actually,
I think these settings have migrated into a config file in the newer kernels.
