2.9.2. JP2: USB 1 and USB 2 power
Type: 3 pin
Default: Pin 1 and Pin 2 Short
This jumper allows you to select the voltage that is supplied to USB 1 and USB 2.
You have two choices: 5 V (pin 1 and pin 2 short) or standby 5 V (pin 2 and pin
3 short). Some USB devices may not follow the standard USB power specifica-
tions. If you are using such a device it may unstable. If you do experience prob-
lems try to change the setting on JP 2. This might help solve this problem.
2.9.3. JP4 and JP5: CPU FSB Clock (optional)
Type: (JP4) 2 pin/(JP5) 2 pin
Default: (JP4) short/ (JP5) open
The Default settings for these jumpers must be kept since they force the
FSB to be 400MHz. Future mainboards based on updated VIA P4X266A chipsets
will be able to support a higher FSB and these jumpers can then be used to se-
lect a desired FSB. Therefore Please retain the current default settings
2.9.4. JP13: Clear CMOS
Type: 3 pin
Default: Pin 1 and Pin 2 Short
If you have made an improper setting in the BIOS setup and your computer is
not functioning, or if you have forgotten your password, you can use this
jumper, JP13, to clear the CMOS and to reconfigure your system.
To clear the CMOS, please follow these instructions:
1.
Turn the system power “OFF” and unplug your computer.
2.
Insert the jumper cap on Pin 2 and Pin 3 for 3 ~ 5 seconds.
3.
Pull out the jumper cap and replace it on Pin 1 and Pin 2.
4.
Turn your PC on and run the BIOS setup program
