5. Jumper
Clear RTC RAM (3-pin J19)
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 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. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear CMOS).
Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap
back to pins 2-3.
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.
Except when clearing the RTC RAM, never remove the cap on jumper J19
default position. Removing the cap will cause system boot failure!

3. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
This connector supports the provided UltraDMA/100/66 IDE hard disk ribbon
cable. Connect the cable’s blue connector to the primary (recommended) or
secondary IDE connector, then connect the gray connector to the
UltraDMA/100/66 slave device (hard disk drive) and the black connector to the
UltraDMA/100/66 master device. It is recommended that you connect non-
UltraDMA/100/66 devices to the secondary IDE connector. If you install two hard
disks, you must configure the second drive as a slave device by setting its
jumper accordingly. Refer to the hard disk documentation for the jumper settings.
BIOS supports specific device bootup. If you have more than two
UltraDMA/100/66 devices, purchase another UltraDMA/100/66 cable. You may
configure two hard disks to be both master devices with two ribbon cables –one
for the primary IDE connector and another for the secondary IDE connector.
1. Pin 20 on each IDE connector is removed to match the covered hole on the
UltraDMAcable connector. This prevents incorrect orientation when you
connect the cables.
2. The hole near the blue connector on the UltraDMA/100/66 cable is intentional.
