This feature requires an ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS. P4BGL-MX P4BGL-MX Keyboard Power Setting 1 2 +5V KBPWR1 3 2 +5VSB (Default) ASUS P4BGL-MX Motherboard 1.11 Connectors This section describes and illustrates the connectors on the motherboard. 1. IDE connectors (40-1 pin PRI_IDE, SEC_IDE) This connector supports the provided UltraDMA100/66 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 UltraDMA100/66 slave device (hard disk drive) and the black connector to the UltraDMA100/66 master device. It is recommended that you connect non-UltraDMA100/66 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 UltraDMA100/66 devices, purchase another UltraDMA100/66 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. 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. For UltraDMA100/66 IDE devices, use an 80-conductor IDE cable. P4BGL-MX SEC_IDE PIN 1 PRI_IDE NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1.

After connecting one end to the motherboard, connect the other end to the floppy drive. (Pin 5 is removed to prevent incorrect insertion when using ribbon cables with pin 5 plug).

Chassis Alarm (4-1 pin CHASSIS1) This lead is for a chassis designed with intrusion detection feature. This requires an external detection mechanism such as a chassis intrusion sensor or microswitch. When you remove any chassis component, the sensor triggers and sends a high-level signal to this lead to record a chassis intrusion event. By default, the pins labeled “Chassis Signal” and “GND” are shorted with a jumper cap. If you wish to use the chassis intrusion detection feature, remove the jumper caps from the pins.

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.

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. 5. USB headers (10-1 pin USB1) USB1 is for the internal USB header that you can connect to the front USB ports.

CPU and Chassis Fan Connectors (3-pin CPUFAN1, CHASFAN1) The two fan connectors support cooling fans of 350mA (4.2 Watts) or a total of 1A (12W) at +12V. Orient the fans so that the heat sink fins allow air flow to go across the onboard heat sinks instead of the expansion slots. The fan wiring and plug may vary depending on the fan manufacturer. Connect the fan cable to the connector matching the black wire to the ground pin.

Lack of sufficient air flow within the system may damage the motherboard components. These are not jumpers! DO NOT place jumper caps on the fan connectors! 7. Internal audio connectors (4-pin AUX1, CD1) These connectors allow you to receive stereo audio input from sound sources such as a CD-ROM, TV tuner, or MPEG card.
