This came up in comp.sys.ibm.pc.hardware. Being a hacker, I would read the
data sheet for the WD1010 (or WD2010) hard disk controller chip. On the
PC-AT (and probably the PC & PC-XT), the controller is strictly I/O mapped,
and lives at 1F0h-1F7h. There's also registers at 3F6 and 3F7, but I think
you can get by without them. Happy hacking.
