(BIOS Setup)
The motherboard supports two programmable Flash ROM chips: 5 Volt and 12
Volt. Either of these memory chips can be updated when BIOS upgrades are re-
leased. Use the Flash MemoryWriter utility to download the new BIOS file into the
ROM chip as described in detail in this section.
All computer motherboards provide a Setup utility program for specifying the sys-
tem configuration and settings. If your motherboard came in a computer system, the
proper configuration entries may have already been made. If so, invoke the Setup
utility, as described later, and take note of the configuration settings for future refer-
ence; in particular, the hard disk specifications.
If you are installing the motherboard, reconfiguring your system or you receive a
Run Setup message, you will need to enter new setup information. This section
describes how to configure your system using this utility.
The BIOS ROM of the system stores the Setup utility. When you turn on the com-
puter, the system provides you with the opportunity to run this program. This ap-
pears during the Power-On Self Test (POST). Press the <Delete> key to call up the
Setup utility. If you are a little bit late pressing the mentioned key(s), POST will
continue with its test routines, thus preventing you from calling up Setup. If you
still need to call Setup, reset the system by simultaneously pressing the <Ctrl>, <Alt>
and <Delete> keys, or by pushing the Reset button on the system case. You can also
restart by turning the system off and then back on again. But do so only if the first
two methods fail.
When you invoke Setup, the CMOS SETUP UTILITY main program screen will
appear with the following options:

The “Load BIOS Defaults” option loads the minimized settings for troubleshooting.
“Load Setup Defaults”, on the other hand, is for loading optimized defaults for
regular use. Choosing defaults at this level, will modify all applicable settings.
A section at the bottom of the above screen displays the control keys for this screen.
Take note of these keys and their respective uses. Another section just below the
control keys section displays information on the currently highlighted item in the list.
Standard CMOS Setup
This “Standard CMOS Setup” option allows you to record some basic system hard-
ware configuration and set the system clock and error handling. If the motherboard
is already installed in a working system, you will not need to select this option
anymore. However, if the configuration stored in the CMOS memory on the board
gets lost or damaged, or if you change your system hardware configuration, you will
need to respecify the configuration values. The configuration values usually get lost
or corrupted when the power of the onboard CMOS battery weakens.
The above screen provides you with a list of options. At the bottom of this screen
are the control keys for use on this screen. Take note of these keys and their respec-
tive uses.
User-configurable fields appear in a different color. If you need information on the
selected field, press the <F1> key. The help menu will then appear to provide you
with the information you need. The memory display at the lower right-hand side of
the screen is read-only and automatically adjusts accordingly.

Hard Disk Drives
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 chan-
nel 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 any the BIOS. If you install the
optional PCI-SC200 SCSI controller card into the motherboard (see section VI for
instructions). If you install other vendor’s SCSI controller card, please 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 en-
ter 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(numberofread/writeheads),PRECOMP (write precompensation), LANDZ
(landing zone), SECTOR (number of sectors) and MODE. The SIZE 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.
The MODEentry 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 be-
low). 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 sup-
port LBA. Large type of drive can only be used with MS-DOS and is very uncom-
mon. Most IDE drives over 528MB support the LBA mode.
Auto detection of hard disks on bootup
For each field: Primary Master, Primary Slave, Secondary Master, and Secondary
Slave, you can select Auto under the TYPE and MODE fields. This will enable auto
detection of your IDE drives during bootup. This will allow you to change your
hard drives (with the power off) and then power on without having to reconfigure
your hard drive type. If you use older hard drives which do not support this feature,
then you must configure the hard drive in the standard method as described above
by the "User" option.
NOTE: After the IDE hard disk drive information has been entered into BIOS, new
IDE hard disk drives must be partitioned (such as with FDISK) and then formatted
before data can be read from and write on. Primary IDE hard disk drives must have
its partition set to active (also possible with FDISK).
