Jumpers
Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.
To erase the RTC RAM:
1.
Turn OFF the computer and unplug the power cord.
2.
Remove the onboard battery.
3.
Move the jumper cap from pins 2-3 (default) to pins 1-2. Keep the
cap on pins 1-2 for about 5~10 seconds, then move the cap back to
pins 2-3.
4.
Re-install the battery.
5.
Plug the power cord and turn ON the computer.
6.
Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
P4S8X-MX
Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!

BIOS setup program
This motherboard supports a programmable firmware chip that you can
update using the provided utility described in section “2.1 Managing and
updating your BIOS.”
Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup.” This section
explains how to configure your system using this utility.
Even if you are not prompted to use the Setup program, you can change
the configuration of your computer in the future. For example, you can
enable the security password feature or change the power management
settings. This requires you to reconfigure your system using the BIOS
Setup program so that the computer can recognize these changes and
record them in the CMOS RAM of the firmware hub.
The firmware hub on the motherboard stores the Setup utility. When you
start up the computer, the system provides you with the opportunity to
run this program. Press <Del> during the Power-On-Self-Test (POST) to
enter the Setup utility; otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, restart the system by pressing
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis.
You can also restart by turning the system off and then back on. Do this
last option only if the first two failed.
The Setup program is designed to make it as easy to use as possible. Being
a menu-driven program, it lets you scroll through the various sub-menus
and make your selections from the available options using the navigation
keys.
•
The default BIOS settings for this motherboard apply for most
conditions to ensure optimum performance. If the system becomes
unstable after changing any BIOS settings, load the default settings
to ensure system compatibility and stability. Select the L o a d
D e f a u l t S e t t i n g s item under the Exit Menu. See section “2.7 Exit
Menu.”

RAID configurations
The SIS 964 southbridge comes with a RAID controller that allows you to
configure Serial ATA hard disk drives as RAID sets. The motherboard
supports the following RAID configurations.
R A I D 0 (Data striping) optimizes two identical hard disk drives to read and
write data in parallel, interleaved stacks. Two hard disks perform the same
work as a single drive but at a sustained data transfer rate, double that of
a single disk alone, thus improving data access and storage. Use of two
new identical hard disk drives is required for this setup.
R A I D 1 (Data mirroring) copies and maintains an identical image of data
from one drive to a second drive. If one drive fails, the disk array
management software directs all applications to the surviving drive as it
contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the
entire system. Use two new drives or use an existing drive and a new drive
for this setup. The new drive must be of the same size or larger than the
existing drive.
J B O D (Spanning) stands for J u s t a B u n c h o f D i s k s and refers to hard
disk drives that are not yet configured as a RAID set. This configuration
stores the same data redundantly on multiple disks that appear as a single
disk on the operating system. Spanning does not deliver any advantage
over using separate disks independently and does not provide fault
tolerance or other RAID performance benefits.
If you want to boot the system from a hard disk drive included in a RAID
set, copy first the RAID driver from the support CD to a floppy disk
before you install an operating system to a selected hard disk drive.
Refer to section “3.4 Creating a RAID driver disk” for details.
3.3.1
Installing hard disks
The motherboard supports Serial ATA hard disk drives. For optimal
performance, install identical drives of the same model and capacity when
creating a disk array.
Installing Serial ATA (SATA) hard disks
To install the SATA hard disks for a RAID configuration:

1.
Install the SATA hard disks into the drive bays.
2.
Connect the SATA signal cables.
3.
Connect a SATA power cable to the power connector on each drive.
