Cards that may cause problems:
Token-Ring Network 16/4 Adapter II. This adapter will NOT work. Do not confuse this card with the IBM Token Ring adapter II (4mbit) which does. It is a DMA/Busmaster adapter for ISA.
3Com TokenLink Velocity ISA. You may or may not get this one to work. I have had reports of people running it without problems, and others who get errors left and right.
