1.7 Jumpers

1. Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the
CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data.
The onboard button cell battery powers the RAM data in CMOS, which include system setup
information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10
seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the Del key during the boot process and enter BIOS setup to re-enter data.
2. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard wake-up feature. Set this jumper to pins 2-
3 (+5 VSB) to wake up the computer when you press a key on the keyboard (the default value is
[Disabled]). This feature requires an ATX power supply that can supply at least 1 A on the +5 VSB
lead, and a corresponding setting in the BIOS (see section "2.5.5 APM Configuration").
