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 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 (approximately). Note that this size is usually slightly larger
than the size of 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.
