Select Block Mode. Select On to allow block mode data transfers.
Select 32-Bit Mode. Select On to allow 32-bit data transfers. Select
the PIO Mode. It is best to select Auto to allow AMIBIOS to determine
the PIO mode. If you select a PIO mode that is not supported by the

Description
The number for a drive with certain identification parameters.
The number of cylinders in the disk drive.
The number of heads.
The actual physical 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 sec-
tors on inner tracks. This parameter is the track number on the disk
surface where write precompensation begins.
This number is the cylinder location where the heads normally park
when the system is shut down.
The number is the cylinder location where the heads normally park
when the system is shut down.
The formatted capacity of the drive is the number of heads times the
number of cylinders times the number of sectors per track times 512
(bytes per sector).
