BIOS SETUP
•
IDE HDD Auto-Detection: Detect the HDD on this channel. If the detection is successful,
it fills the remaining fields on this menu.
•
IDE Primary/Secondary Master/Slave: We recommend that you select “AUTO” for
all drives. The BIOS can automatically detect the specifications during POST (Power
On Self Test) while the system boots. You can also choose “Manual” to set the
specifications yourself. The “None” setting means there is no device installed on this
IDE channel.
•
Access Mode: “CHS”, “LBA”, “Large”, or “Auto”.
-
CHS: Maximum number of cylinders, heads, and sectors supported are 1024,
16, and 63 respectively.
-
LBA (Logical Block Addressing): During drive access, the IDE controller transfers
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
more than 1024 cylinders.
-
Large: For drives that do not support LBA and have more than 1024 cylinders.
-
Auto: The BIOS automatically determines the optimal access mode.
•
Capacity: Disk drive capacity. Note that this size is slightly greater than the size of
a formatted disk given by the disk-checking program.
•
Cylinder: Number of cylinders
•
Head: Number of heads
•
Precomp: Write precompensation cylinder
•
Landing Zone: Landing zone
•
Sector: Number of sectors
