Hour: 00 to 23
Minu7te: 00 to 59
Second: 00 to 59
HardDisks
This option is used to set the current time for all IDE hard disks in the system (PrimaryMaster/Slave; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster; SecondaryMaster). /Slave; SecondaryMaster/Slave) types in the system. The options are described below:
Aut allows the system to automatically detect and set the hard disk type at boot.
None: No hard disk is installed.
User: Allows the user to set the parameters of the hard disk. These include CYLS, HEAD, PRECOMP, LANDZ, etc. These specifications are detailed in the manuals that come with the drive, such as the number of heads.
[Special Note]: BIOS does not support SCSI hard drive setup.
As for the MODE options, there are three:
NORMAL mode: The traditional standard mode, which supports hard drive capacities up to 528MB.
LBA (LogicalBlockAddressingMode) mode: Suitable for hard drives with capacities greater than 528MB, and supports the LogicalBlock LARGE mode: When the hard drive capacity exceeds 528MB, and the hard drive capacity exceeds 528MB, and the hard drive capacity exceeds 528MB, and the hard drive capacity exceeds 528MB, and the hard drive capacity exceeds 528MB, the hard drive capacity exceeds 528MB. This option is available when the hard drive capacity exceeds 528MB and the hard drive or operating system does not support LBA mode.
