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

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.
Description
The number for a drive with certain identification parameters.
The number of cylinders in the disk drive.
The number of heads.
The size of a sector gets progressively smaller as the track
diameter diminishes.
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.
number where write precompensation begins.
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.
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)
4-5
Yet each sector must still hold 512 bytes.
This parameter is the track
