•
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 recommand that you select “AUTO” for
all drives. The BIOS can automatically detect the specifications during POST while
the system boots. You can also choose “Manual” to set the specifications yourself.
“None” indicates that 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 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
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.
