4. BIOS SETUP

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

detects 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:

• 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 precompensation

factor, landing zone, and number of sectors, Drives whose specifications do not

accommodate any pre-defined type are classified as type USER.

• 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.

• Cyls: Number of cylinders

• Head: Number of herds

• Precomp: Write precompensation cylinder

• Landz: Landing zone

• Sector: Number of sectors

• Mode: Auto, Normal, large, or LBA

• Auto: The BIOS automatically determines the optimal mode.
