4. Expansion slots The motherboard has three PCI slots and one Accelerated Graphics Port (AGP) slot. To install and configure an expansion card: 1. Install an expansion card following the instructions that came with the chassis. 2. Turn on the system and change the necessary BIOS settings, if any. 3. Assign an IRQ to the card. Refer to the tables below. 4. Install the drivers and/or software applications for the expansion card according to the card documentation. Standard interrupt assignments

PCI slots There are three (3) 32-bit PCI slots on this motherboard. The slots support PCI cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specifications. The figure below shows a typical PCI card installed into a slot. AGP slot This motherboard has an Accelerated Graphics Port (AGP) slot that supports AGP 8X/4X cards. When you buy an AGP card, make sure that you ask for one with +1.5V specification. Note the notches on the card golden fingers to ensure that th

5. Jumpers 1. Clear CMOS (3-pin CLRTC) This jumper allows you to clear the RAM data in CMOS, except the system date and time. The RAM data in CMOS, is powered by the onboard button cell battery. To erase the CMOS RAM: 1. Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 2-3 (Default) to pins 1-2 (Clear CMOS). Keep the cap on pins 1-2 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

2. Clear Password (3-pin CLPWD) This jumper allows you to clear the BIOS setup password. To erase the BIOS setup password: 1. Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 2-3 (Default) to pins 1-2 (Clear Password). Keep the cap on pins 1-2 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 key during the boot process and enter the BIOS setup to set a new password. CLPWD 12 23 A7V

6. Connectors This section describes and illustrates the internal connectors on the motherboard. 1. Floppy disk drive connector (34-1 pin FLOPPY) This connector supports the provided floppy drive ribbon cable. 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.) FLOPPY NOTE: Orient the red markings on the floppy ribbon cable to PIN 1.

3. IDE connectors (40-1 pin PRIMARY_IDE, SECONDARY_IDE) This connector supports the provided UltraDMA 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 device (hard disk drive) and the black connector to the UltraDMA100 master device. It is recommended that you connect non-UltraDMA100 devices to the secondary IDE connector. If you install two hard disks, you must configure the

4. CPU and Chassis Fan Connectors (3-pin CPU_FAN, CHA_FAN) The fan connectors support cooling fans of 350mA~740mA (8.88W max.) or a total of 1A~2.22A (26.64W max.) at +12V. Connect the fan cables to the fan connectors on the motherboard, making sure that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Lack of sufficient air flow within the system may damage the motherboard components. These are not jumpers! D

6. USB headers (10-1 pin FRONT_USB1) If the USB ports on the rear panel are inadequate, a USB header is available for additional USB ports. The USB header complies with USB 2.0 specification that supports up to 480 Mbps connection speed. This speed advantage over the conventional 12 Mbps on USB 1.1 allows faster Internet connection, interactive gaming, and simultaneous running of high-speed peripherals. You may connect a USB module to the USB header. FRONT_USB1 FRONT_USB2 A7V8X-LA(KELUT) 1 1 A7V

8. IEEE 1394 connector (10-1 pin FRONT_1394) This connector is for a 10-to-6-pin 1394 serial connector cable that connects to a 1394 module. Attach the 10-1 pin cable plug to this connector, and the 6-pin cable plug to the 1394 module. You may also connect a 1394-compliant internal hard disk to this connector. NEVER connect a USB cable to any of the IEEE 1394 connectors. Doing so will damage the motherboard! 1 A7V8X-LA(KELUT) TPA+ TPA- GND GND FRONT_1394 TPB+ TPB- +12V +12V GND A7V8X-LA(KELUT) F
