Harddisks (HDD)

This option is used to set all IDE hard drives in the system (Primarymaster/slave; Secondarymaster/slave) type. The options are described below:

Auto: Allows the system to automatically detect and set the type of drive when booting.

None: The hard drive is not installed.

User: Allows the user to set the relevant parameters of the drive itself. Includes cyls (number of magnetic cylinders), head (read-write head count), Precomp (write pre-compensation), Landz (put position). The specifications attached to the hard drive are stopped by the heads of the actuator.

[Please note that the]:bios does not support SCSI HDD settings.]

There are three types of mode options:

Normal mode: Supports HDD capacity up to 528MB for traditional standard mode.

LBA (logicalblockaddressingmode) mode: For those with a hard drive capacity exceeding and supporting logical block Addressing (LBA) capabilities.

Large mode: This option is available when the HDD capacity exceeds 528MB and the hard drive or operating system does not support LBA mode.
