IDE HDD Auto-Detection
The BIOS supports up to two IDE drives. This section does not
show information about other IDE devices, such as a CD-ROM
drive, or other hard drive types, such as SCSI drives.
NOTE: We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal
operating mode of almost all IDE hard drives. When you select
AUTO for a hard drive, the BIOS will detect its specifications
IDE Primary/Secondary Master/Slave
If you do not want to select "AUTO", other methods of selecting
the drive type are available:
1.NONE: No drive type to be selected.
2.Manual: This will allow you to manually set the drive type you

Access Mode
- Auto: The BIOS automatically determines the optimal mode.
- CHS: This allows the user to enter their own hardware values.
- 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, significantly
improving data transfer rates. For drives with greater than 1024
cylinders.
