Your computer can recognize a number of
specific hard-disk drives. Each is assigned
a drive-type number that is stored in
NVRAM. The hard-disk drive(s) specified
in your computer’s System Setup pro-
gram must match the actual drive(s)
installed in the computer. The System
Setup program also allows you to specify
physical parameters (cylinders, heads,
write precomp, landing zone, and capaci-
ty) for drives not included in the table of
drive types stored in NVRAM.
