[net.micro.pc] Adding a hard disk to the AT...

cenkl@faron.UUCP (cenkl@faron.research) (12/20/85)

The old IBM ATs (<= 20M hard disks) support 14 distinct hard disk drive 
types (1 - 14) with drive type 15 left open for user defined drives.
Assuming that I have a drive that is not among the first 14,
how do I enter the correct drive type entry (# of cylinders, # of heads, etc.)
given that I know all of the necessary data? The Fall BYTE describing such a
procedure is quite vague on this point. Where in ROM can the table of
drive type entries be found on both the old and new ATs?
Does anybody know which drives drive type 20 corresponds to under the new 
AT ROMs? Thanks in advance.
