Following are the parameters stored in a PC's BIOS setup memory that describe the configuration of the hard disks in the system. SCSI hard disks are usually not identified in the setup memory.|
TYPE There are 46 hard disk types, numbered 1
to 46, that include all the required
parameters below. Since they cover
earlier drives that only go up to 152MB,
the user-configurable Type 47 is usually
chosen and the remaining parameters are
entered manually or are automatically
detected (all new drives are detected).
CYLINDERS Number of cylinders.
HEADS Number of read/write heads.
WPCOM Write precompensation track.
ZONE Cylinder used for parking heads.
SECTORS Number of sectors per track.
CAPACITY Total capacity derived from above
(heads X cylinders X sectors X 512)
