3. HARDWARE SETUP
4) Clear RTC RAM
These two solder points allow 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 RAM data in CMOS,
that include system setup information such as system passwords, is powered by
the onboard button cell battery.
To erase the RTC RAM: (1) unplug the computer, (2) short the solder points, (3)
turn ON the computer, (4) hold down the <Del> key during the boot process and
enter BIOS setup to re-enter data.

5) USB Device Wake-up Jumpers (3-pin USBPWR1, USBPWR2)
These jumpers allow you to enable or disable the USB feature on the motherboard.
Set to Enable if you wish to use the USB devices to wake up the computer. This
feature requires an ATX power supply that can supply at least 2A on the +5VSB
lead. The default setting for both USBPWR1 and USBPWR2 is DISABLE.
NOTES:
1. Before setting either of these jumpers to ENABLE, make sure that you have
the appropriate power supply, otherwise the computer does not power up.
2. When using the Suspend-to-RAM feature, set these jumpers to ENABLE.
3. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal working conditions or in sleep mode.
