I am looking for ROM dumps for the NI card as well. I've dumped ROMs
from most other cards. I've placed there temporarily here:
I've disassembled the ones I have. They all appear to be based on the
same CIO reference firmware, mostly compiled with a C compiler, share
75% of code between them, do not support PIO access other than to return
the card id code and accept a slot number, and communicate with the host
OS through in/out FIFOs at an address in memory based on the card id.
