100MHz / 100MHz and 133MHz / 133MHz Synchronous Host/DRAM Clock
Support: CPU frequency can operate at 133MHz while system memory
operates at 133MHz.
Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master buses to memory to CPU.
SDRAM Optimized Performance: This motherboard supports Synchronous
Dynamic Random Access Memory (SDRAM), which increases the data transfer
rate of 800MB/s max using PC133-compliant SDRAMs.
ACPI Ready: ACPI (Advanced Configuration and Power Interface) provides
more Energy Saving Features for future operating systems (OS) supporting OS
Direct Power Management (OSPM) functionality. With these features implemented in the OS, PCs can be ready around the clock, yet satisfy all the energy
saving standards. To fully utilize the benefits of ACPI, an ACPI-supported OS,
such as Windows 98, must be used.
New Compliancy: Both the BIOS and hardware levels of the motherboard meets
PC 99 compliancy. The new PC 99 requirements for systems and components are
based on the following high-level goals: Support for Plug and Play compatibility
and power management for configuring and managing all system components,
and 32-bit device drivers and installation procedures for Windows 95/98/NT/ME/
2000/XP.

2. HARDWARE SETUP
2.3 Hardware Setup Procedure
Before using your computer, you must complete the following steps:
• Check Motherboard Settings
• Install Memory Modules
• Install the Central Processing Unit (CPU)
• Install Expansion Cards
• Connect Ribbon Cables, Panel Wires, and Power Supply
2. H/W SETUP
Motherboard Settings
WARNING! Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you
should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do not have
one, touch both of your hands to a safely grounded object or to a metal object, such as
the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or connectors, or
other components.
4. Place components on a grounded antistatic pad or on the bag that came with the component whenever the components are separated from the system.
5. Ensure that the ATX power supply is switched off before you plug in or remove the
ATX power connector on the motherboard.

2.4 System Memory (DIMM)
2. H/W SETUP
System Memory
NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are
available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 16, 32, 64, 128MB, 256 or 512MB to form a memory size
between 16MB and 1GB. One side (with memory chips) of the DIMM takes up one
row on the motherboard.
To use the chipset’s Error Checking and Correction (ECC) feature, you must use a
DIMM with 9 chips per side (standard 8 chips/side + 1 ECC chip).
Install memory in any combination as follows:
IMPORTANT
• For optimum signal integrity, inserting the DIMMs in the following order is
recommended: DIMM1, DIMM2.
• SDRAMs used must be compatible with the current PC133/PC100 SDRAM
specification.

2.5.1 General DIMM Notes
•
•
•
•
This motherboard supports SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
This motherboard does NOT support registered memory.
SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips.
Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32,
64, 128, 256, 512MB.

2. HARDWARE SETUP
2.4.2 DIMM Memory Installation
Insert the module(s) as shown. Because the number of pins are different on either
side of the breaks, the module will only fit in the orientation shown. DIMM modules are longer and have different pin contact on each side and therefore have a
higher pin density. SIMM modules have the same pin contact on both sides.

2.5 Central Processing Unit (CPU)
The motherboard provides a Socket 462 or Socket A for CPU installation. A fan and
heatsink should be attached to the CPU to prevent overheating. Purchase and install
a fan and heatsink before turning on the system.

LOCK
NOTCH
A7V-VM Socket A
1. Locate the Socket 462 and open it by pulling
the lever gently sideways away from the socket.
Then lift the lever upwards. The socket lever
must be fully opened (90 to 100 degrees).
2. Insert the CPU with the correct orientation. The
notched corner of the CPU must be oriented
toward the inner corner of the socket base
nearest to the lever hinge.
CAUTION! The CPU fits in one orientation
and should drop easily into place. Do not force
the CPU into the socket to avoid bending the
pins. If the CPU does not fit, check its
alignment and look for bent pins.
3. Once completely inserted, press the CPU firmly and close the socket lever until it
snaps into its locked position.
4. Place the CPU fan and heatsink on the CPU. The heatsink should entirely cover
the CPU. Carefully attach the heatsink locking brace to the plastic clips on the
socket base. With the added weight of the CPU fan and heatsink locking brace,
no extra force is required to keep the CPU in place.
CAUTION! Take care not to scrape the motherboard surface when mounting a
clamp-style processor fan, or else damage may occur. When mounting a heatsink
onto your CPU, make sure that exposed CPU capacitors do not touch the
heatsink, or else damage may occur! Refer to heatsink/CPU documentation.
NOTE! Do not forget to set the correct Bus Frequency and Multiple (available
only on unlocked processors) to avoid start-up problems.

2.6 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.
2. H/W SETUP
Expansion Cards
2.6.1 PCI 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 system’s cover and the bracket plate on the slot you
intend to use. Keep the bracket for possible future use.
3. Carefully align the card’s connectors and press firmly.
4. Secure the card on the slot with the screw you removed above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary
7. Install the necessary software drivers for your expansion card.
2.6.2 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: Ribbon cables should always be connected with the red stripe to
Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on
floppy disk drives. Check the connectors before installation because there may
be exceptions. IDE ribbon cables must be less than 46 cm (18 in.), with the
second drive connector no more than 15 cm (6 in.) from the first connector.
1) PS/2 Mouse Connector (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.

These connectors support the provided UltraDMA/66 IDE hard disk ribbon cable.
Connect the cable’s blue connector to the motherboard’s primary (recommended)

UltraDMA/66 slave device (hard disk drive) and the black connector to your
UltraDMA/66 master device. It is recommended that non-UltraDMA/66 devices
be connected to the secondary IDE connector. If you install two hard disks, you
must configure the second drive to Slave mode by setting its jumper accordingly. Please refer to your hard disk documentation for the jumper settings. BIOS
now supports specific device bootup. (Pin 20 is removed to prevent inserting
in the wrong orientation when using ribbon cables with pin 20 plugged).
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 the BIOS
