Right, I looked at that, but, from my 'observation' of how the qd6580 DOS
driver works, the qd6580.c driver may be doing more than it thinks. I'll know
more when I get a copy of DOSEMU which logs I/O accesses.
Yes, my 'Vision' brand VLB super I/O card has two IDE ports on it. One seems
to be an EIDE port and the second seems to be a normal ISA IDE port. I haven't
fully verified this.
