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 life of me remember the address to use
in Debug. I know how to use Debug; I've done 100's of LL formats - just not in the
last dozen years or so. Does Anybody remember?? Please email off-list. Thank you.... My
HDD is working, I just want to set it up right from scratch. (In case anybody's
wondering, I do a LL format on IDE drives before using them, too.) Bill Pileggi

I'm fairly certain there is no formatter in ROM, it requires a program
loaded from floppy. I don't know if any generic program will work or if you
need a special formatter.

included on the IBM "Advanced Diagnostics" diskette

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

FWIW most clones used an offset of 5 (C800:5, CC00:5, etc) but Adaptec used
CCC (C800:CCC, CC00:CCC).

For a Xebec board, there isn't a single BIOS address that you can just
jump to with the debug command. You have to poke info into several
registers with debug, which 'kicks off' the controller card to do a
low-level format of the drive. It silently picks up and the hard drive
light goes active, then eventually goes out. With no feedback, but I
believe there's a register you can then read with debug to see that it
formatted properly. It's a rather 'blind' formatting routine. I don't
know if I have a list of the commands to give anymore. I believe you
can 'reverse engineer' it by reading the I/O register commands and
what-not in the technical reference for the card. Which I remember
seeing published somewhere once. Again I may have it, but it's waaaay
back in the archives.
Somebody needs to write an 'early PC/PC-clone hard drive FAQ' that
contains all this stuff. OR is there one already?
