IV. BIOS SETUP Time To set the time, highlight the "Time" field and then press either / or / to set the current time. Follow the hour, minute and second format. Valid values for hour, minute and second are: (Hour: (00 to 23), Minute: (00 to 59), Second: (00 to 59). NOTE: You can bypass the date and time prompts by creating an AUTOEXEC.BAT file. For information on how to create this file, please refer to the MS-DOS manual. Hard Disks This field records the specifications for all non-SCSI hard disk drives installed in your system. The onboard PCI IDE connectors provide Primary and Secondary channels for connecting up to four IDE hard disks or other IDE devices. Each channel can support up to two hard disks; the first of which is the "master" and the second is the "slave". Specifications for SCSI hard disks need not to be entered here since they operate using device drivers and are not supported by the BIOS. If you install other SCSI controller cards, refer to their respective documentations on how to install the required SCSI drivers. For IDE hard disk drive setup, you can: • Use the Auto setting for detection during bootup. • Use the IDE HDD AUTO DETECTION in the main menu to automatically enter the drive specifications. • Enter the specifications yourself manually by using the "User" option. The entries for specifying the hard disk type include CYLS (number of cylinders), HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ (landing zone), SECTOR (number of sectors) and MODE. The SIZE field automatically adjusts according to the configuration you specify. The documentation that comes with your hard disk should provide you with the information regarding the drive specifications. The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI drives. This entry provides three options: Normal, Large, LBA, or Auto (see below). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow larger IDE hard disks; set it to Large for drives over 528MB that do not support LBA. Large type of drive can only be used with MS-DOS and is very uncommon. Most IDE drives over 528MB support the LBA mode. IV. BIOS SETUP Standard CMOS ASUS P2-99B User's Manual 43

nels for connecting up to four IDE hard disks or other IDE devices. Each channel
can support up to two hard disks; the first of which is the “master” and the second is
the “slave”.
Specifications for SCSI hard disks need not to be entered here since they operate
using device drivers and are not supported by the BIOS. If you install other SCSI
controller cards, refer to their respective documentations on how to install the re-
quired SCSI drivers.
For IDE hard disk drive setup, you can:
•
Use the
Auto
setting for detection during bootup.
•
Use the IDE HDD AUTO DETECTION in the main menu to automatically
enter the drive specifications.
•

The entries for specifying the hard disk type include
CYLS
(number of cylinders),
HEAD

field auto-
matically adjusts according to the configuration you specify. The documentation
that comes with your hard disk should provide you with the information regarding
the drive specifications.
