If you select
User
, you will need to know the information listed below. Enter the
information directly from the keyboard and press <Enter>. This information should
be included in the documentation of your hard disk vender or the system
manufacturer.
TYPE drive type
CYLS. number of cylinders
HEADS number of heads
PRECOMP write precom
LANDZONE landing zone
SECTORS number of sectors
MODE mode type
If you select type Auto , BIOS will Auto-Detect the HDD & CD-ROM drives at the
POST stage and show the IDE for HDD & CD-ROM drives.
If the controller of HDD interface is
ESDI , the selection shall be Type 1 .
If the controller of HDD interface is
SCSI
, the selection shall be
None
.
If a hard disk has not been installed, select None and press Enter.
＊
Write Pre compensation -
The size of a sector gets progressively smaller
as the track diameter diminishes, but each sector must still hold 512 bytes.
Write Pre compensation circuitry on the hard disk compensates for the
physical difference in sector size by boosting the write current for sectors on
inner track.
＊
Landing Zone -
The cylinder location where the heads will normally park
when the system is shut down.
＊
Capacitor
= (Number of heads) x (Number of cylinders) x (Number of
sectors per track) x (512 Bytes per sector)
＊
Mode
For IDE hard drives, the BIOS provides three modes to support both normal
IDE hard disks and drives larger than 528MB:
Auto mode
(default) - detect and enter the IDE device type during bootup.
Normal mode - for IDE drives smaller than 528MB.
LBA mode - provides LBA (Large Block Addressing) function for mass
capacity hard disk that larger than 528MB and up to 8.4GB (Giga Bytes).
Large mode - some mass capacity hard disks operate in large mode and do
not support LBA function for above mentioned mass capacity hard disks.
Large mode is a new specification which may not be fully supported by all
operation systems (MS-DOS does support it now, but is uncommon)
