Hello,
for the Amiga, there are a couple of nearly-IDE interfaces, that don't contain
the 0x3f6 register (interupt enable, soft reset on write; alternate status
on read).
Whould it work to leave out the hard part of the probing, and replace them
by something more soft, like, issue ATA identify and ATAPI identify commands
to both units and see what answers?
This would also make the infamous 4IDE adapters work... they select a 2nd
half-IDE "bus" instead of the upper register.
Regards,
Ignatios
