1. JP14 Clear CMOS
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. JP27/28 Keyboard/Mouse Wakeup Jumper
This motherboard provides USB and PS2 keyboard / mouse wake-up function. You can use JP27 / JP28 to enable or disable this function, which could resume your system from suspend mode with keyboard or mouse installed. JP28 controls 1 st
USB channel, and JP27 controls 2 nd
USB channel. The factory default setting is set to “Disable”(1-2), and you may enable this function by setting the jumper to 2-3.
3. ATX Power Connectors
This motherboard comes with a 20-pin and 4-pin ATX power connector as shown below.
Make sure you plug in the right direction. We strongly recommend you to insert the 4-pin connector before connecting the 20-pin connector.
4. Installing CPU & System Fan
Plug in the CPU fan cable to the 3-pin CPUFAN1 connector. If you have chassis fan, you can also plug it in SYSFAN2 or SYSFAN3 connector.
Note: Some CPU fans do not have sensor pin so they cannot support fan monitoring.
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. The default setting is "table select mode". You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.

Warning: Intel 845GV supports maximum 533MHz system bus and
66MHz AGP clock; higher clock setting may cause serious system damage.
This motherboard provides six USB connectors to link USB devices, such as mouse, keyboard, modem, printer, etc. There are four ports on the PC99 back panel. You can use proper cable to connect other USB connectors to the back panel or front panel of chassis.
7. 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.
Front Audio Connector
8. 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, make sure to have the correct orientation when you plug in the
9. Connecting Front Panel Cable
Attach 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.
Locate the power switch cable from your ATX housing. It is
2-pin female connector from the housing front panel. Plug this connector to the soft-power switch connector marked SPWR .

10. S/PDIF (Sony/Philips Digital Interface) Connector
S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides impressive audio quality through optical fiber and allows you to enjoy digital audio instead of analog audio. 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. 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.
Same as outputs, you can also connect RCA or optical audio products to input connectors on the module and have the voice or music come out from your computer. However, you must have a S/PDIF supported speaker/amplifier/decoder with S/PDIF digital input/output to connect to the S/PDIF digital input/output to make the most out of this function.
(User Upgrade Optional)
11. Super 5.1 Channel Audio Effects
This motherboard comes with an ALC650 CODEC, which supports high quality of 5.1
Channel audio effects, bringing you a brand new audio experience. On the strength of the innovative design of ALC650, you're able to use standard line-jacks for surround audio output without connecting any external module. To apply this function, you have to install the audio driver in the Bonus Pack CD as well as an audio application supporting 5.1 Channel. Picture bellow represents the standard location of all speakers in 5.1Channel sound track. Please connect the plug of your front speakers to the green “Speaker out” port, rear speakers’ plug to the blue “Line in” port and both of the center and subwoofer speakers to the red “MIC in” port.
12. COM2 Connector
This motherboard provides two serial ports. One of them is on back panel connector, and the other is on the upper middle of board. With proper cable, you can connect it to the back panel of chassis.
13. Support 10/100 Mbps LAN Onboard
On the strength of RealTek RTL8100BL LAN controller on board, which is a highly-integrated
Platform LAN Connect device, it provides 10/100M bps Ethernet for office and home use, the
Ethernet RJ45 connector is located on top of USB connectors. The green LED indicates the link mode, it lights when linking to network and blinking when transferring data. The orange
LED indicates the transfer mode, and it lights when data is transferring in 100Mbps mode. To enable or disable this function, you may simply adjust it through BIOS.

It is strongly recommended NOT to turn off the power or run any application during
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.
If you encounter any trouble while booting your system, follow the procedures accordingly to resolve the problem.
Turn off the power and unplug the AC power cable, then remove all of the addon cards and cables, including VGA, IDE, FDD, COM1,
COM2 and Printer.
Make sure if the jumper settings for CPU and DRAMs are correct.
Install the VGA card. Then connect your monitor and keyboard.
Turn on the power, and check if the power supply and CPU fan work properly.
The problem was probably caused by power supply or motherboard failure. Please contact your reseller or local distributor for repairing.
Check if there is display.
Perhaps your VGA card or monitor is defective.
Press Ctrl, and Alt key at the same time, hold them and then press Del to see if the system reboots.
During system rebooting, press Del to enter BIOS Setup. Choose
“Load Setup Default".
It is very possible that your keyboard is defective.
The problem should be caused by the
IDE cables or HDD itself.
Turn off the system and re-connect the IDE cable.
Check if the system can reboot successfully.
Re-install Windows 95, Windows 98 or Windows NT.
