[comp.sys.ibm.pc] Lowlevel format for an IBM controller

murillo@sigi.Colorado.EDU (Rodrigo Murillo) (02/25/88)

More fun with low level formats...
Can anyone tell me how to get to the ROM format routines for an
IBM HD controller on a 3270PC?  Here are the numbers from the board:

IBM 62x0776    108668     FAB 104757   Rev D

The drive is an IBM Model WD25.  I have tried the routines at
C800:5, C800:CCC, C800:CCCC  and they just lock up the computer.

Does anyone know of an IBM Tech number where one can pick the brains
of some of the IBM techies?  (not the service reps, ha!)
