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 The size of a sector gets progressively smaller as the track
Precompensation 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.
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)
Boot Sector Virus Protection
This setting allows you to prevent any data from being written the boot sector of
the hard drive. While this may prevent viruses from infecting your system, you
may need to change information here when installing new programs. The options

Setting Description

AMIBIOS tests all system memory. AMIBIOS waits up to 40
seconds for a READY signal from the IDE hard disk drive.
AMIBIOS waits for .5 seconds after sending a RESET signal
to the IDE drive to allow the IDE drive time to get ready again.
