Jumpers
Setting the BIOS Configuration Jumper
Always turn off the power to the computer before moving the jumper. Moving the
jumper with the power on may result in unreliable computer operation.
▪
The diagram below shows the location of the jumper block. The 3-pin jumper block (3-pin CLRTC)
determines the BIOS Setup program’s mode. The normal default position for the jumper is pins 1-
2. To clear the CMOS memory , the jumper is set to pins 2-3.
Clearing Passwords
This procedure assumes that the board is installed in the computer and the configuration jumper
block is set to normal mode.
Observe the precautions in " Before You Proceed ". 1.
Turn off all peripheral devices connected to the computer. Turn off the computer. Disconnect
the computer’s power cord from the AC power source (wall outlet or power adapter).
2.
Remove the computer cover.
3.
Find the 3-pin CLRTC jumper block (see Location of the Bios Configuration Jumper Block
above).
4.
Place the jumper on pins 2-3 for about 5 to 10 seconds, then move the cap back to pins 1-2. 5.
Replace the cover, plug in the computer, turn on the computer, and allow it to boot . During
the boot process, hold down the key to enter the BIOS setup.
6.
Except when clearing the RTC RAM , never remove the cap from the CLRTC jumper default position.
Removing the cap will cause system boot failure!
▪
If the steps above do not help, remove the onboard battery and move the jumper again to clear
the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.
▪
Due to the chipset behavior, AC power off is required to enable C.P.R. function. You must turn off
and on the power supply or unplug and plug the power cord before rebooting the system.
