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!

2. ATX power connectors (20-pin ATX_POWER1, 4-pin ATX12V)

These connectors connect to an ATX 12V power supply. The plugs from the power supply are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit.

In addition to the 20-pin ATXPWR connector, this motherboard requires that you connect the 4-pin ATX +12V power plug to provide sufficient power to the

CPU.

Make sure that your ATX 12V power supply can provide 8A on the +12V lead and at least 1A on the +5-volt standby lead (+5VSB). The minimum recommended wattage is 230W, or 300W for a fully configured system. The system may become unstable and may experience difficulty powering up if the power supply is inadequate.

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

UltraDMA cable 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.

NOTE: Orient the red markings

(usually zigzag) on the IDE ribbon cable to PIN 1.
