ATX V2.03 Power Supply is strongly recommended for mainboard run­ning with 2GHz or higher CPU.

To set up Power Supply on this mainboard:

1. Connect the on-board Main Power Connector (20-pin) to the Main
Power Connector (20-pin) of an ATX Power Supply which can be of
the latest version 2.03 model, and then connect the square-shaped
+12V Power Connector on board to the square-shaped +12V Power
Connector of the Power Supply.

Warning: Both the Main Power Connector and the +12V Power
Connector should be connected to Power Supply; otherwise, the
system may either not start or damaged.

2. This ATX Power Supply should be able to provide at least 720mA/
+5V standby power for Wake On Lan function.

A 3-pin Jumper

If a pin-header (of 2 or more pins) is
designed in such a way that its pins
can be closed or linked together to
set up a specific function,
is called a jumper in this manual.

A 2-pin
Jumper
Cap

The conductor inside the cap
links two header-pins together.

• A Jumper is usually but not necessarily given a “JpX” legend.

• In the Jumper setting diagram, the jumper pins covered with

black marks stand for closed pins with jumper cap.

SL-915P-G Chapter 4 BIOS Setup

4-1 About BIOS Setup

BIOS stands for Basic Input and Output System. It was once called
ROM BIOS when it was stored in a Read-Only Memory (ROM) chip
Now manufacturers would like to store BIOS in EEPROM which means
Electrically Erasable Programmable Memory. BIOS used in this series
of mainboard is stored in EEPROM, and is the first program to run when
you turn on your computer.

BIOS setup is an interactive BIOS program that you need to run when:

1. Changing the hardware of your system. (For example: installing a
new Hard Disk etc.)

2. Modifying the behavior of your computer. (For example: changing
the system time or date, or turning special features on or off etc.)

3. Enhancing your computer’s behavior. (For example: speeding up
performance by turning on shadowing or cache)

4-2 To Run BIOS Setup

First access BIOS setup menu by pressing < DEL > key after “POST” is
complete ( before OS is loaded ). BIOS will then display the following
message:

DEL:SETUP

4-3 About CMOS

CMOS is the memory maintained by a battery. CMOS is used to store
the BIOS settings you have selected in BIOS Setup. CMOS also
maintains the internal clock. Every time you turn on your computer, the
BIOS Looks into CMOS for the settings you have selected and configures
your computer accordingly. If the battery runs out of power, the CMOS
data will be lost and POST will issue a “CMOS invalid” or “CMOS
checksum invalid” message. If this happens, you have to replace the
battery and check and configure the BIOS Setup for the new start.

4-4 The POST ( Power On Self Test )

POST is an acronym for Power On Self Test. This program will test all
things the BIOS does before the operating system is started. Each of
POST routines is assigned a POST code, a unique number which is
sent to I/O port 080h before the routine is executed.

44

SL-915P-G Chapter 4 BIOS Setup

4-5 To Update BIOS

• System BIOS is incorporated into a Flash memory component. Flash

BIOS allows user to upgrade BIOS without the need to replace an EPROM
component.

• The Upgrade Utility can be loaded on a floppy diskette for upgrading

saving, and verifying the system BIOS. The Update Utility can also be run
from a hard disk drive or a network drive.

• Normally, to update BIOS is unnecessary if the system is working fine.

Users should only update BIOS when incompatible problems are encoun­tered or new features have to be added to system.

• Please follow the steps below for updating the sys­ tem BIOS:

Step 1. Please visit the board maker’s website, download the zip files
of the latest BIOS and AMI flash utility “afudos.exe” for your mainboard.
After unzipping, the BIOS file format will be *.ROM, of which “ * ” stands
for the specific BIOS file name.

Step 2. Create a bootable diskette. Then copy the BIOS file and AMI
flash utility “afudos.exe” into the diskette.

Step 3. Insert the diskette into drive A, boot your system from the
diskette.

Step 4. Under “ A “ prompt, type “ afudos /i*.ROM “ and then press
<Enter> to run BIOS update program. Please note that there should be
a space and “/i” between afudos and *.ROM. (*.ROM depends on your
mainboard model and version code. Instead of typing “*”, you should
type the specific file name for your specific mainboard). For example,
you may type “afudos /iMP005.rom”.

Step 5. When the message “Flash ROM Update Completed - Pass.”
appears, please restart your system.

Step 6. You will see a message “CMOS Memory Size Wrong” during
booting the system. Press <Del> or <F1> to run CMOS setup utility,
then reload “Load Failsafe Defaults” or “Load Optimal Defaults” and
save this change.
