************************************************************************
- Support for MCA EtherWORKS cards added 11-3-98.
+ Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
Verified to work with up to 2 DE212 cards in a system (although not
fully stress-tested).
- Currently known bugs/limitations:
-
- Note: with the MCA stuff as a module, it trusts the MCA configuration,
- not the command line for IRQ and memory address. You can
- specify them if you want, but it will throw your values out.
- You still have to pass the IO address it was configured as
- though.
