I want to perform a low-level format on my Seagate ST-225 MFM hard
drive - it has the Xebec (IBM) 1210 controller card. I cannot for the
Real IBM ST506 controllers don't have a low-level format routine in the
ROM, you have to load a program from floppy. It was on the IBM Advanced
Diagnostics disk (IIRC), I assume there's something suitable on the web
somewhere.
For _most clone_ hard disk controllers, the address is C800:5 BTW
