3.5 System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). Three sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory size between 8MB to 1.5GB. One side (with memory chips) of the DIMM takes up one row on the motherboard. This motherboard also supports NECs Virtual Channel (VC) SDRAMs. Memory speed setup is recommended through BIOS SDRAM Configuration under Chipset Features Setup. IMPORTANT (see General DIMM Notes below for more): SDRAMs used must be compatible with the current Intel PC133 SDRAM specification. DO NOT attempt to mix PC133 SDRAMs with VCM SDRAMs. The motherboard only supports PC100 / PC133 DIMMs or VC SDRAMs for system memory. Registered DIMMs are not supported. Install memory in any combination as follows:

Voltage Key Position 5.0V 3.3V Reserved
3.6 Central Processing Unit (CPU)
The motherboard provides a Socket 462 or Socket A for CPU installation. The CPU that came with the motherboard should have a fan and heatsink attached to it to prevent overheating. If this is not the case, then purchase and install a set before you turn on your system. WARNING! Make sure that the heatsink is mounted tightly against the processor. Make sure also that there is sufficient air circulation across the processors heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard. You may install an auxiliary fan, if necessary. To install a CPU, first turn off your system and remove its cover. Locate the Socket 462 and open it by first pulling the lever sideways away from the socket, then upwards. The socket lever must be fully opened (90 to 100 degrees) when installing or removing the CPU. Insert the CPU with the correct orientation. The notched corner should be oriented toward the blank space on the socket nearest the lever. The CPU has a corner pin for two of the four corners, and will only fit in the orientation as shown. Ensure that the CPU is exactly parallel to the socket base so the pins make good contact and are not bent. Take care not to exert too much force, but press the CPU down gently into the slot. Once completely inserted, close the socket lever while holding down the CPU. Make sure the CPU fan and heatsink cover the entire face of the CPU. With the added weight of the CPU fan and heatsink locking brace, no extra force is required to keep the CPU in place. NOTE: If necessary, do not forget to set the correct Bus Frequency and Multiple for your processor or else boot-up may not be possible. Frequency multiple settings are available only on unlocked processors. CAUTION! Be careful not to scrape the motherboard surface when mounting a clamp-style processor fan or else damage may occur to the motherboard.

3.7 Expansion Cards

WARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.
3.7.1 Expansion Card Installation Procedure
1. Read the documentation for your expansion card and make any necessary hardware or software settings for your expansion card, such as jumpers. 2. Remove your computer systems cover and the bracket plate on the slot you intend to use. Keep the bracket for possible future use. 3. Carefully align the cards connectors and press firmly. 4. Secure the card on the slot with the screw you removed above. 5. Replace the computer systems cover. 6. Set up the BIOS if necessary (such as IRQ xx Used By Legacy Drive: Yes in 4.4.3 PCI Configuration) 7. Install the necessary software drivers for your expansion card.

3.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclusively assigned to one use. In a standard design, there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. If your motherboard has PCI audio onboard, an additional IRQ will be used. If your motherboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free. IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support Share IRQ or that the cards do not need IRQ assignments. Conflicts will arise between the two PCI groups that will make the system unstable or cards inoperable. The following table lists the default IRQ assignments for standard PC devices. Use this table when configuring your system and for resolving IRQ conflicts.
Standard Interrupt Assignments

Mic (pink) allows microphones to be connected for inputting voice.
9) Primary (Blue) / Secondary (Black) IDE Connectors (40-1 pin PRIMARY IDE and SECONDARY IDE) (40-1 pin PRIMARY ATA100 and SECONDARY ATA100) These connectors support the IDE hard disk ribbon cables supplied with the motherboard. Connect the cables blue connector to the motherboards primary IDE connector (recommended) or the secondary IDE connector. Then connect the opposite end of the cable to your UltraDMA/100/66 device (hard disk drive). A second slave hard disk may be attached to the intermediate connector on the cable. If a second hard disk drive is connected, you may reset its jumper to Slave mode. Refer to your hard disk documentation for the jumper settings. It is recommended that non-UltraDMA/100/66 devices be connected to the secondary IDE connector. BIOS now supports specific device bootup (see 4.4.1 Advanced CMOS Setup). (Pin 20 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 20 plugged). If you have more than two UltraDMA100/66 devices, you will need to purchase another UltraDMA100/66 cable. The A7V133 motherboard is supplied with two extra onboard IDE connectors: one Primary ATA-100 IDE and one Secondary ATA-100 IDE. You can use them to setup the RAID 0 or 1 arrays and to support extra IDE devices. For the purposes of RAID arrays, adjust the jumper settings: see 3.4 Motherboard Setting, ATA-100/RAID 0 or 1, page 20. A total of eight hard-disks, two on each IDE connector, can be connected to the A7V133 TIP: For high-performance and RAID 0 or 1 set ups, you should always setup two hard disks with two separate ribbon cables, one for the primary IDE connector and another for the secondary IDE connector. Usually, both disks may be set to the Master settings: see 5.4 Software Setup for more information about RAID. Also, you may install one operating system on an IDE drive and another on a SCSI drive and select the boot disk through 4.4.1 Advanced CMOS Setup. NOTE: UltraDMA/100 is backward compatible with DMA/66 and DMA/33 and with all with existing DMA devices and systems, so there is no need to upgrade current EIDE/IDE drives and host systems. IMPORTANT: UltraDMA66 and UltraDMA100 IDE devices require a 40-pin 80-conductor cable and RAID arrays only operate with such cables.

This function requires an ACPI OS and driver support. 25) Reset Switch Lead (2-pin RESET) This 2-pin connector connects to the case-mounted reset switch for rebooting your computer without having to turn off your power switch. This is a preferred method of rebooting to prolong the life of the systems power supply. 26) ATX Power Switch Lead (2-pin PWRSW) The system power is controlled by a momentary switch connected to this lead. Pressing the button once will switch the system between ON and SOFT OFF. Pushing the switch while in the ON mode for more than 4 seconds will turn the system off. The system power LED shows the status of the systems power. 27) System Management Interrupt Lead (2-pin SMI) This allows the user to manually place the system into a suspend mode or Green mode, where system activity is decreased to save electricity and expand the life of certain components when the system is not in use. This 2-pin connector connects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the Turbo Switch. SMI is activated when it detects a short to open moment and therefore leaving it shorted will not cause any problems. This may require one or two presses depending on the position of the switch. Wake-up can be controlled by settings in the BIOS but the keyboard will always allow wake-up (the SMI lead cannot wake up the system). 44 ASUS A7V133 Users Manual

4. BIOS SETUP

4.1 Managing and Updating Your BIOS
4.1.1 Upon First Use of the Computer System

It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. To determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper lefthand corner of your screen during bootup. Larger numbers represent a newer BIOS file. 1. Type FORMAT A:/S at the DOS prompt to create a bootable system floppy disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the disk. 2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CDROM drive) to copy AFLASH.EXE to the just created boot disk. NOTE: AFLASH works only in DOS mode. It will not work with DOS prompt in Windows and will not work with certain memory drivers that may be loaded when you boot from your hard drive. It is recommended that you reboot using a floppy. 3. Reboot your computer from the floppy disk. NOTE: BIOS setup must specify Floppy as the first item in the boot sequence. 4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
IMPORTANT! If unknown is displayed after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory Writer utility. ASUS A7V133 Users Manual 47

3.5 System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). Three sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory size between 8MB to 1.5GB. One side (with memory chips) of the DIMM takes up one row on the motherboard. This motherboard also supports NECs Virtual Channel (VC) SDRAMs. Memory speed setup is recommended through 4.4.1 Chip Configuration. IMPORTANT (see General DIMM Notes below for more): SDRAMs used must be compatible with the current Intel PC133 SDRAM specification. DO NOT attempt to mix PC133 SDRAMs with VCM SDRAMs. The motherboard only supports PC100 / PC133 DIMMs or VC SDRAMs for system memory. Registered DIMMs are not supported. Install memory in any combination as follows:

3.6 Central Processing Unit (CPU)
The motherboard provides a Socket 462 or Socket A for CPU installation. The CPU that came with the motherboard should have a fan and heatsink attached to it to prevent overheating. If this is not the case, then purchase and install a set before you turn on your system. WARNING! Make sure that the heatsink is mounted tightly against the processor. Make sure also that there is sufficient air circulation across the processors heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard. You may install an auxiliary fan, if necessary. To install a CPU, first turn off your system and remove its cover. Locate the Socket 462 and open it by first pulling the lever sideways away from the socket, then upwards. The socket lever must be fully opened (90 to 100 degrees) when installing or removing the CPU. Insert the CPU with the correct orientation. The notched corner should be oriented toward the blank space on the socket nearest the lever. The CPU has a corner pin for two of the four corners, and will only fit in the orientation as shown. Ensure that the CPU is exactly parallel to the socket base so the pins make good contact and are not bent. Take care not to exert too much force, but press the CPU down gently into the slot. Once completely inserted, close the socket lever while holding down the CPU. With the added weight of the CPU fan and heatsink locking brace, no extra force is required to keep the CPU in place. The CPU fan and heatsink should cover the entire face of the CPU. NOTE: If necessary, do not forget to set the correct Bus Frequency and Multiple for your processor or else boot-up may not be possible. Frequency multiple settings are available only on unlocked processors. CAUTION! Be careful not to scrape the motherboard surface when mounting a clamp-style processor fan or else damage may occur to the motherboard.

3.7 Expansion Cards

WARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.
3.7.1 Expansion Card Installation Procedure
1. Read the documentation for your expansion card and make any necessary hardware or software settings for your expansion card, such as jumpers. 2. Remove your computer systems cover and the bracket plate on the slot you intend to use. Keep the bracket for possible future use. 3. Carefully align the cards connectors and press firmly. 4. Secure the card on the slot with the screw you removed above. 5. Replace the computer systems cover. 6. Set up the BIOS if necessary (see 4.4.3 PCI Configuration) 7. Install the necessary software drivers for your expansion card.

1) PS/2 Mouse Connector (Green 6-pin PS2KBMS) The system will direct IRQ12 to the PS/2 mouse if one is detected. If one is not detected, expansion cards can use IRQ12. See PS/2 Mouse Function Control in 4.4 Advanced Menu.
PS/2 Mouse (6-pin Female)
2) PS/2 Keyboard Connector (Purple 6-pin PS2KBMS) This connection is for a standard keyboard using an PS/2 plug (mini DIN). This connector will not allow standard AT size (large DIN) keyboard plugs. You may use a DIN to mini DIN adapter on standard AT keyboards.
PS/2 Keyboard (6-pin Female)

3. H/W SETUP Connectors

3) Universal Serial BUS Ports 0 & 1 (Black two 4-pin USB) Two USB ports are available for connecting USB devices.
Universal Serial Bus (USB) 1
4) Serial Port Connectors (Teal/Turquoise 9-pin COM1 / COM2) Two serial ports can be used for pointing devices or other serial devices. For setting up these ports, see Onboard Serial Port 1 in 4.4.2 I/O Device Configuration for settings.
COM1 COM2 Serial Ports (9-pin Male)
5) Parallel Port Connector (Burgundy 25-pin PRINTER) You can enable the parallel port and choose the IRQ through Onboard Parallel Port (see 4.4.2 I/O Device Configuration). NOTE: Serial printers must be connected to the serial port.

8) Floppy Disk Drive Connector (34-1 pin FLOPPY) This connector supports the provided floppy drive ribbon cable. After connecting the single end to the board, connect the two plugs on the other end to the floppy drives. (Pin 5 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 5 plugged).
NOTE: Orient the red markings on the floppy ribbon cable to PIN 1.
A7V Floppy Disk Drive Connector
7) Audio Port Connectors (Three 1/8 GAME_AUDIO) (optional) Line Out (lime) can be connected to headphones or preferably powered speakers. Line In (light blue) allows tape players or other audio sources to be recorded by your computer or played through the Line Out (lime). Mic (pink) allows microphones to be connected for inputting voice.
9) Primary (Blue) / Secondary IDE Connectors (40-1 pin PRIMARY IDE/SECONDARY IDE) (40-1 pin PRIMARY ATA100/SECONDARY ATA100) These connectors support the provided IDE hard disk ribbon cables. Connect the cables blue connector to the motherboards primary (recommended) or secondary IDE connector, and then connect the corresponding gray connector to your UltraDMA/100 / UltraDMA/66 slave device (hard disk drive) and the black connector to your UltraDMA/100 / UltraDMA/66 master device. It is recommended that non-UltraDMA/100 / Ultra/66 devices be connected to the secondary IDE connector. NOTE: UltraDMA/100 is backward compatible with DMA/66, DMA/33, and DMA and with existing DMA devices and systems so there is no need to upgrade current EIDE/IDE drives and host systems. If you install two hard disks, you must configure the second drive to Slave mode by setting its jumper accordingly. Refer to your hard disk documentation for the jumper settings. BIOS now supports specific device bootup (see 4.6 Boot Menu). (Pin 20 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 20 plugged). If you have more than two UltraDMA/100 / UltraDMA/66 devices, you will need to purchase another UltraDMA/100 / UltraDMA/66 cable. NOTE: The hole near the blue connector on the UltraDMA/100 / UltraDMA/66 cable is intentional. TIP: You may configure two hard disks to be both Masters with two ribbon cables one for the primary IDE connector and another for the secondary IDE connector. You may install one operating system on an IDE drive and another on a SCSI drive and select the boot disk through 4.6 Boot Menu. IMPORTANT: UltraDMA/66 and UltraDMA/100 IDE devices require a 40-pin 80-conductor cable to be enabled.

7. The utility starts to program the new BIOS information into the flash ROM. The boot block will be updated automatically only when necessary. This will minimize the chance that a failed update will prevent your system from booting up. When the programming is finished, Flashed Successfully will be displayed.
8. Follow the onscreen instructions to continue.
WARNING! If you encounter problems while updating the new BIOS, DO NOT turn off your system since this might prevent your system from booting up. Just repeat the process, and if the problem still persists, update the original BIOS file you saved to disk above. If the Flash Memory Writer utility was not able to successfully update a complete BIOS file, your system may not be able to boot up. If this happens, your system will need servicing.

4.2 BIOS Setup Program
This motherboard supports a programmable EEPROM that can be updated using the provided utility as described in 4.1 Managing and Updating Your BIOS. The utility is used if you are installing a motherboard, reconfiguring your system, or prompted to Run Setup. This section describes how to configure your system using this utility. Even if you are not prompted to use the Setup program, at some time in the future you may want to change the configuration of your computer. For example, you may want to enable the Security Password Feature or make changes to the power management settings. It will then be necessary to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the EEPROM. The EEPROM on the motherboard stores the Setup utility. When you start up the computer, the system provides you with the opportunity to run this program. This appears during the Power-On Self Test (POST). Press <Delete> to call up the Setup utility. If you are a little bit late in pressing the mentioned key, POST will continue with its test routines, thus preventing you from calling up Setup. If you still need to call Setup, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressing the Reset button on the system chassis. You can also restart by turning the system off and then back on again. But do so only if the first two methods fail. The Setup program has been designed to make it as easy to use as possible. It is a menu-driven program, which means you can scroll through the various sub-menus and make your selections among the predetermined choices. To access the BIOS Setup program, press the <Delete> key after the computer has run through its POST.

7.3 Glossary

is the IEEE designation for the high performance serial bus at 12.5, 25 or 50MBytes/sec speeds. This serial bus defines both a back plane physical layer and a point-to-point cable-connected virtual bus. The primary application of the cable version is the integration of I/O connectivity at the back panel of personal computers using a low-cost, scalable, high-speed serial interface. The 1394 standard also provides new services such as live connect/disconnect capability for external devices including disk drives, printers and hand-held peripherals such as scanners and cameras. This is a new standard to complement the slower USB interface and to compete with the more expensive SCSI interface. AC97 (Audio Codec '97) AC '97 is the next step in enabling PCs with audio quality comparable to consumer electronics devices. The specification defines new cost-effective options to help integrate the components necessary to support next-generation auto-intensive PC applications such as DVD, 3-D multiplayer gaming and interactive music. The specification also defines new extensions supporting modem and docking to help both desktop and mobile manufacturers adopt these new technologies more quickly and cost-effectively. This specification uses software emulation to compete with the PCI SoundBlaster specification. ACPI (Advanced Configuration and Power Interface) The ACPI specification defines a cross-platform interface designed to support many operating systems. ACPI defines a flexible and abstract hardware interface that provides a standard way to integrate power management features throughout a PC system, including hardware, operating system and application software. This enables the system to automatically turn ON and OFF peripherals such as CD-ROMs, network cards, hard disk drives, and printers, as well as consumer devices connected to the PC such as VCRs, TVs, phones, and stereos. With this technology, peripherals will also be able to activate the PC. For example, inserting a tape into a VCR can turn on the PC, which could then activate a large-screen TV and high-fidelity sound system. AGP (Accelerated Graphics Port) An interface specification that enables high-performance 3D graphics on mainstream PCs. AGP was designed to offer the necessary bandwidth and latency to perform texture mapping directly from system memory. Bus PCI AGP 1X AGP 2X AGP 4X Bus Frequency 33MHz 66MHz 66MHz 66MHz Bandwidth 33MHz 66MHz 133MHz 266MHz Data Transfer Rate 133MByte/sec 266MByte/sec 512MByte/sec 1024MByte/sec
