1. JP14 Clear CMOS
Everything you need to boot this
motherboard is included in this
Easy Installation Guide. For more
information, a complete Online
User's Manual can be found in the
Bonus Pack CD Disc. Thanks for
the help of saving our earth.
PART NO: 49.89X02.011 DOC. NO: AK75P-EG-E0204A
You can clear CMOS to restore system default setting. To
clear the CMOS, follow the procedure below.
1. Turn off the system and unplug the AC 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 pin 1 & pin 2.
5. Connect ATX power cable back to connector PWR2.
Tip: When should I Clear CMOS?
1. Boot fail because of overclocking…
2. Forget password…

2. S/PDIF (Sony/Philips Digital Interface) Connector
S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides impressive
quality through optical fiber and allows you to enjoy digital audio instead of analog audio. Normally there are
two S/PDIF outputs as shown, one for RCA connector, the most common one used for consumer audio
products, and the other for optical connector with better audio quality. Through a specific audio cable, you
can connect the S/PDIF connector to other end of the S/PDIF audio module, which bears S/PDIF digital
output. However, you must have a S/PDIF supported speaker with S/PDIF digital input to connect to the
S/PDIF digital output to make the most out of this function.

5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through the
BIOS setup, and no jumpers or switches are needed.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio
Warning: SIS 745 Chipset supports maximum 266MHz (EV6)
system bus and 66MHz AGP clock; higher clock setting may cause
serious system damage.
4. JP21 FSB/PCI Clock Ratio
This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, i
f
you are not overclockers, we recommend you to set at the default setting. Additionally, this
motherboard also provides “1MHz Stepping Adjustment” feature for overclockers to adjus
t
CPU FSB frequency via BIOS setup program. Based on the CPU type, the adjustmen
t
range has two levels: 100~123 (FSB=100, such as Athlon 800), 124~200 (FSB=133, such
as Athlon 1000) MHz for your choosing. You may also choose a specific FSB frequenc
y
ranging from 100~124 (say, 105, 110, 115 for example) and 133~166 with reference to a
frequency table in BIOS setup program. If you fix the CPU FSB frequency by JP21, the
“1MHz Stepping Adjustment” range will be changed and following JP21 setting. To adjus
t

Warning: High CPU core voltage may be able to

7. Dr. Voice
The Dr. Voice is a great feature of this motherboard, which can identifies what kind o
f
problems had occurred in the operating system. It can even clearly “tell” whether there is a
component issue or an installed issue, such as CPU, memory module, VGA, PCI add-on
card, FDD, HDD or keyboard by voice. The Dr. Voice provides four kinds of language
versions, English, German, Japanese and Chinese for your choosing. You can selec
t
preferred language version by JP15 & JP16
j
umpers. However, if you want to disable this
function, you may also set JP1 and JP2 to pin 2-3 to disable to buzzer and speaker from
making out voices respectively.
Connect 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy connector FDC and
IDE connector. Be careful of the pin1 orientation. Wrong orientation may cause system
damage.

onboard. The IEEE 1394a provides data transfer rate up to 400Mb/s, while USB is jus
t
12Mb/s. Hence, the IEEE 1394 interface can connect with the devices that needs high
data transferring performance, such as digital camera, scanner or others IEEE 1394a
devices. Please use the proper cable to connect to devices.

Caution: By updating your motherboard, you are taking a risk
of BIOS flash failure. If your motherboard is working stable,
and there are no major bugs that had been fixed by a latter
BIOS revision, we recommend that you DO NOT try to upgrade
your BIOS.
If you intent on upgrading, PLEASE BE SURE to get the right
BIOS revision for the right motherboard model to avoid any
p
ossibility failure.
10. Front Audio Connector
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.

11. Support Six USB Connectors
This motherboard provides six USB connectors to connect USB devices, such as mouse,
keyboard, modem, printer, etc. There are two connectors on the PC99 back panel. You
can use proper cable to connect other USB connectors to the back panel or front panel of
chassis.

12. BIOS Upgrade under Windows environment
With outstanding R&D ability of AOpen, we now bring you a whole new BIOS Flash wizard
---- EZWinFlash. With an eye to users convenience, EZWinFlash combines the BIOS
binary code and flash module together, so the only thing you have to do is just clicking on
the utility you downloaded from web and let it helps you complete the flash process
automatically. EZWinFlash detects your motherboard and checks the BIOS version
cleverly to prevent your system from any possible failure. Moreover, EZWinFlash has been
taken into consideration to go with any windows platform you might be using, no matter i
f
you’re using Windows 95/98, 98SE/ME, NT4.0/2000, or even the latest Windows XP.
In the meanwhile, in order to provide a much more user-friendly operating environment,
AOpen EZWinFlash is natively designed to have multi-language function to provide easier
way for users’ usage in changing BIOS setting.

Note: The model name on this BIOS picture is for reference only. It may not be the
exact model name.

A
fter you finish the setting of jumpers and connect correct cables. Power on
and enter the BIOS Setup, press <Del> during POST (Power On Self Test).
Choose "Load Setup Defaults" for recommended optimal performance.
14. Power-on and Load BIOS Setup
15. AOpen Bonus Pack CD 17. BIOS Upgrade
AOpen Easy Flash is more user-friendly than traditional flash method. The BIOS binary
file and flash routine are combined together and you simply run a single file to complete
the flash process.
1. Download new BIOS upgrade zipped file from AOpen's web site. For example,
AK75P102.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, AK75P102.BIN & AK75P102.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:> AK75P102 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 Setup” and finish the BIOS upgrade.
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.
16. Installing Onboard Sound Driver
You can use the autorun menu of Bonus CD disc. Choose the utility and driver and selec
t
model name.
Del
Warning: Please avoid of using "Load
Turbo Defaults", unless you are sure
y
our system components (CPU, DRAM,
HDD, etc.) are good enough for turbo

.
This motherboard comes with an A’C97 CODEC, you can find the audio driver from the
Bonus Pack CD disc auto-run menu.

If you encounter any trouble to boot you system, follow the procedures
accordingly to resolve the problem.
