BIOS SETUP
•
IDE HDD Auto-Detection: Detect the HDD on this channel. If the detection is
successful, the remaining fields on this menu are automatically filled in.
•
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” and “CHS” in
Access Mode to set the specifications yourself. The “None” setting means there is
no device installed on the indicated IDE channel.
•
Access Mode: “CHS”, “LBA”, “Large”, or “Auto”.
−−−−−
CHS: Maximum number of Cylinders, Heads, Precomp, Landing Zone, and Sectors
supported are 65535, 255, 65535, 65535, and 255, 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.

a formatted disk given by the disk-checking program.
