BIOS SETUP

1.Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive type 1 through 45.

2.Select “USER” and enter values into each drive parameter field.

3.Use the “IDE HDD AUTO DETECTION” function in Main Menu.

Here are the brief explanations 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 accommo- date any pre-defined type are classified as type “USER”.

*SIZE : Disk drive capacity (approximately). 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 respectively.

-LARGE : For drives that do not support LBA and have more than 1024 cylinders.

-LBA (Logical Block Addressing) : During drive access, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address. This will significantly improve data transfer rates for drives with greater than 1024 cylinders.
