1. System / CPU Thermal Solution
With the increasing performance of system, the components nowadays always generate enormous heat in
your system, such as CPU, VGA card, HDD, and so on. This motherboard provides two thermal solutions
for users to detect the temperature of any components, which respectively are system thermal senso
r
connector and CPU thermal sensor inside CPU socket.
Tip: When should I Clear CMOS?
1. Boot fail because of overclocking…
2. Forget password…
3. Troubleshooting…
You can clear CMOS to restore system default setting.
To clear the CMOS, follow the procedure below.
1. Turn off the system and unplug theAC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pins 1-2.
5. Connect ATX power cable back to connector PWR2.

4. Installing CPU and Fan
Plug CPU to AMD Socket 462 connector. Be
careful of CPU orientation. Plug in the fan
cable to the 3-
p
in CPU FAN or FAN connector.
Note: Some CPU fans do not have
sensor pin, so that cannot support
fan monitorin
g
.
3. Front Audio
If the housing has been designed with an audio port on the front panel, you’ll be able to
connect onboard audio to front panel through this connector. By the way, please remove
5-6 and 9-10 jumper caps from the Front Audio Connector before connecting the cable.
Please do not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on
the front panel.

5. Setting CPU Voltage and Frequency
Full-range Auto-Detect CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be
automatically detected and the range is from 1.1V to 1.85V.
Supported CPU Frequency
Core Frequency = CPU Bus Clock * CPU Ratio
EV6 Bus Speed = CPU Bus Clock x 2
PCI Clock = CPU Bus Clock / Clock Ratio
A
GP Clock = PCI Clock x 2
Warning: VIA®ProSavage KM133 / KM133A chipset supports
100/133MHz FSB and 66MHz AGP clock with CPU running at 100MHz (If
CPU runs at 133MHz, VIA®ProSavage KM133A chipset can supports
133MHZ FSB and 66 MHz AGP clock only), higher clock setting may
cause serious s
y
stem dama
g
e.
Tip: If your system hangs or fails to boot because of overclocking,
simply use <Home> key to restore the CPU default frequency.

9. Connecting IDE and Floppy Cable
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector. Be careful of the pin1 orientation. Wrong orientation may cause system
damage.
A
ttach the power LED, speaker, and reset
switch connectors to the corresponding pins.
If you enable “Suspend Mode” item in BIOS
Setup, the ACPI & Power LED will keep
flashing while the system is in suspend
mode.
7. Connecting Front Panel Cable

This JP21 jumper is used to specify the relationship of PCI and FSB clock. Please set the
j
umper based on your CPU FSB. For CPU FSB of 100MHZ, you may set JP21 to “1-2”
pin and for CPU FSB of 133MHz, you may set the pin to “2-3”.
8. Dr. LED (Optional)
The Dr. LED can easily show what kind of problems you may incur on your system during
assembly. It can clearly indicate whether there is a component issue or an installed issue
by the 8 LEDs on the front panel of PC-Doctor. This can helps you quickly self-diagnose
your system status.

10. Connecting IrDA Connector
The IrDA connector can be configured to support wireless infrared module, with this
module and application software such as Laplink or Windows 95 Direct Cable Connection,
the user can transfer files to or from laptops, notebooks, PDA devices and printers. This
connector supports HPSIR (115.2Kbps, 2 meters) and ASK-IR (56Kbps).
Install the infrared module onto the IrDA connector and enable the infrared function from
BIOS Setup, UART mode select, make sure to have the correct orientation when you plug
in the IrDA connector.
This motherboard supports four USB ports. Two of them are on back panel connector,
the other two are on the left-bottom area of this motherboard. With proper cable, you
can connect them to front panel.

Warning: If you want
to uninstall the VIA

p
lease remove the
A
GP card driver first.
Otherwise, the screen
may go black at
rebooting after the
un-installation.
Note: Installing this
Bus Master IDE
driver may cause
Suspend to Hard
Drive failure.
13. Installing VIA 4 in 1 driver
You can install the VIA 4 in 1 driver, VIA ATAPI Vendor Support Driver, VIA AGP, IRQ
Routing Driver, VIA Registry (INF) Driver) from the Bonus Pack CD disc Autorun menu.

14. Power-on and Load BIOS Setup
A
fter you finish the setting of jumpers and connect correct cables. Powe
r
on and enter the BIOS Setup, press <Del> during POST (Power-On
Self Test). Choose "Load Setup Defaults" for recommended optimal
performance.
Del
15. Autorun Menu from Bonus CD Disc
You can use the autorun menu of Bonus CD disc. Choose the utility and driver and select
model name.
17. BIOS Upgrade
A
Open Easy Flash is a little different than traditional flash method. The BIOS binary file
and flash routine are linked together and you simply run a single commend to complete
the flash process.
Below are the steps for easy flashing procedures: (applies for Award BIOS ONLY)
1. Download new BIOS upgrade zipped file from AOpen's web site.
For example, AK33M102.ZIP.
2. Run shareware PKUNZIP (http://www.pkware.com/) which supports miscellaneous
operation systems to extract the binary BIOS file and the flash utility.
Or Winzip (http://www.winzip.com/) in Windows environment.
3. Save the unzipped file into a bootable floppy disk.
For example, AK33M102.BIN & AK33M102.EXE
4. Reboot the system to DOS mode without loading any memory handler (such as
EMM386) or device driver. It needs around 520K free memory space.
5. Execute A:> AK33M102 and the program will do the rest of it.
DO NOT turn off the power during FLASH PROCESS until you are asked to!!
6. Reboot system and press <Del> to enter BIOS setup, Choose “Load Setup
Defaults"
,
then “Save & Exit Setu
p
”. Done!
16. Installing Onboard Sound Driver
This motherboard comes with an AD 1885 AC97 CODEC and the sound controller is in
VIA South Bridge chipset. You can find the audio driver from the Bonus Pack CD disc
autorun menu.
Warning: The upgrade of new BIOS will permanently replace your original BIOS
content after flashing. The original BIOS setting and Win95/Win98 PnP information
will be refreshed and you probably need to re-configure your system.
Warning: Please avoid of using "Load
Turbo Defaults", unless you are sure
your system components (CPU, DRAM,
HDD, etc.) are good enough for turbo
settin
g
.

If you encounter any trouble to boot you system, follow the
procedures accordingly to resolve the problem.
Part Number and Serial Number
The Part Number and Serial number are printed on bar code label. You can find this ba
r
