<PgUp> or <PgDn> key to increment the setting, or type the desired value into the
field.
4.3.3 Hard Disks
The BIOS supports up to four IDE drives. This section does not show information
about other IDE devices, such as a CD-ROM drive, or about other hard drive types,
such as SCSI drives.
NOTE : We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal operating mode of
almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS
detect its specifications during POST, every time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive
type are available:
1. Match the specifications of your installed IDE hard drive(s) with the
preprogrammed values for drive types 1 through 45.
2. Select USER and enter values into each drive parameter field.
3. Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:
Ø
Type: The BIOS contains a table of pre-defined drive types. Each defined
drive type has a specified number of cylinders, number of heads, write pre-
compensation factor, landing zone, and number of sectors, Drives whose
specifications do not accommodate any pre-defined type are classified as type
USER.
Ø
Size: Disk drive capacity (approximate). Note that this size is usually slightly
greater than the size of a formatted disk given by a disk-checking program.
Ø
Cyls: Number of cylinders
Ø
Head: Number of heads
Ø
Precomp: Write pre-compensation cylinder
Ø
Landz: Landing zone
Ø
Sector: Number of sectors
Ø
Mode: Auto, Normal, large, or LBA
Ø
Auto: The BIOS automatically determines the optimal mode.
Ø
Normal: Maximum number of cylinders, heads, and sectors supported are
1024, 16 and 63.
Ø
Large: For drives that do not support LBA and have more than 1024 cylinders.
Ø
LBA (Logical Block Addressing): During drive accesses, the IDE controller
transforms the data address described by sector, head, and cylinder number
into a physical block address, significantly improving data transfer rates. For
drives with greater than 1024 cylinders.
