Jp28 Keyboard/Mouse Wakeup Jumper - AOpen i915GMm-HF Easy Installation Manual

Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through
1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU external
frequency x CPU Ratio. However, all CPU now selling in the market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but only change CPU
FSB clock to achieve overclocking.
(Users do the overclocking at their own risk!!)
BIOS Setup > Frequency / Voltage Control > CPU Bus Frequency
CPU Ratio 4x, 5x... 17x, 18x, 20x
CPU FSB FSB = 400MHz - 533MHz by 1MHz

Note: With CPU speed changing rapidly, there might be faster CPU on the market by the time
you received this installation guide. This table is kindly for your references only.
Tip: When you fail to overclock, you could:
1. Clear CMOS (JP14) to restore the default setting.
2. After turning power on, press "Home" immediately until the screen
appears.
Warning: Intel 915GM chipset support maximum 533MHz (133MHz*4)
system bus; higher clock setting may cause serious system damage.

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.

JP28 Keyboard/Mouse Wakeup Jumper

This motherboard provides keyboard / mouse wake-up function. You can use JP28
to enable or disable this function, which could resume your system from suspend
mode with keyboard or mouse. The factory default setting is "Disable" (1-2), and
you may enable this function by setting the jumper to 2-3.

Tip: When should I Clear CMOS?
1. Boot fails because of overclocking...
2. Forget password...
