Time
To set the time, highlight the “Time” field and then press either
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 Sec-
ondary channels for connecting up to four IDE hard disks or other IDE de-
vices. 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 bythe 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 automati-
cally 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 cylin-
ders), 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.
