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 heads

_ 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.

_ Normal: Maximum number of cylinders, heads, and sectors supported are 1024, 16,

and 63.

_ Large: For drives that do not support LBA and have more than 1024 cylinders.

_ 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.
