How to Configure
IDE
Select Type. Select Auto to let BIOS determine the parameters. Click on OK when
BIOS displays the drive parameters. Select LBA Mode. Select On if the drive has a
capacity greater than 540 MB. 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 BIOS to determine the PIO mode.
If you select a PIO mode that is not supported by the IDE drive. The drive will not
work properly. If you are absolutely certain that you know the drive’s PIO mode.
Select PIO mode 0-4, as appropriate.
Standard MFM
Select Type. You must know the drive parameters. Select the drive type that
exactly matches your drive’s parameters.
Non-Standard MFM
Select Type. If the drive parameters do not match the drive parameters listed for
drive types 1 - 46. Select User and enter the correct hard disk drive parameters.
ENTERING DRIVE PARAMETERS
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.
Precompensation
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 sectors on inner tracks.
Landing Zone
This parameter is the track number on the disk surface where write
precompensation begins.
Sectors
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).
