rd BIOS Setup Program
Type (Auto/User/None): Use the fields under the Type column to determine the
method you will use to configure the IDE devices. If you choose Auto, BIOS will
automatically detect and make optimal settings for most IDE hard drives.
The mainboard manufacturer recommends that you choose Auto for all
drives.
Choose User to define your own drive type manually. You must enter values
indicated in the table below into each drive parameter field. This information should
be included in the documentation from your hard disk vendor or system manufacturer:
Cyls/Head/Sector: The number of Cylinders, Heads, and Sectors can usually be found
written on the top of the hard disk. If you have a relatively new hard drive, entering
this information alone is usually sufficient for normal hard disk operation. The hard
disk will not work properly if you enter improper information for these categories.
Precomp: Older hard drives (i.e., MFM or RLL drives) have the same number of
sectors per track at the innermost tracks as at the outermost tracks. Thus, the data
density at the innermost tracks is higher and the bits are lying closer together. Even
though the physical size of a sector gets progressively smaller as the track diameter
diminishes, each sector must still hold 512 bytes. Write precompensation circuitry
compensates for the difference in sector size by boosting the write current for inner
track sectors.
Landz: This defines the address of the landing zone and is only used for older hard
drives which do not have an auto-parking feature.
Mode: If the Type value is not None for any device, you must set the Mode value
for that device. There are four different Mode values: Auto, Normal, Large, and
LBA.
Auto - BIOS detects and enters the IDE drive type during boot up.
Normal - for IDE drives that meet the old IDE specification which support
a maximum capacity of 528MB (1024 cylinders, 16 heads, and 63 sectors).
