Standard Setup
Hard Disk C: Type
Hard Disk D: Type
Select one of these hard disk drive icons to configure the drive named in the option. A scrollable screen that lists all
valid disk drive types is displayed. Select the correct type and press <Enter>. If the hard disk drive is an IDE drive,
select Detect C: or Detect D: from the Utility section of the WinBIOS Setup main menu to have AMIBIOS
automatically detect the IDE drive parameters and report them to this screen.
Entering Drive Parameters
You can also enter the hard disk drive parameters. The drive parameters are:
Parameter Description
Type The number for a drive with certain identification parameters.
Cylinders The number of cylinders in the disk drive.
Heads The number of heads.
Write
Precompensation
The size of a sector gets progressively smaller as the track
diameter diminishes. Yet each sector must still hold 512 bytes.
Write precompensation circuitry on the hard disk compensates
for the physical difference in sector size by boosting the write
current for sectors on inner tracks. This parameter is the track
number where write precompensation begins.
Landing Zone This number is the cylinder location where the heads will
normally park when the system is shut down.
Sectors The number of sectors per track. MFM drives have 17 sectors
per track. RLL drives have 26 sectors per track. ESDI drives
have 34 sectors per track. SCSI and IDE drive may have even
more sectors per track.
Capacity The formatted capacity of the drive is (Number of heads) x
(Number of cylinders) x (Number of sectors per track) x (512
bytes per sector)
