4 GB for registered modules and full AGP 3.0 capability bus utilization including 2x, 4x, and 8x mode transfers, SideBand Addressing, Flush/Fence
commands and pipelined grants.
The VT8235 Southbridge supports standard intelligent peripheral controllers
such as USB v2.0/1.1 and Universal HCI v2.0/1.1 compliant, real time clock
with 256 byte extended CMOS, integrated bus-mastering dual full-duplex direct-sound AC97 link compatible sound system and full System Management
Bus (SMBus) interface.
The L7VTA is equipped with advanced full set of I/O ports, such as dual
channel IDE interfaces, a floppy controller, two high-speed serial port, an
EPP/ECP capable bi-directional parallel port connector, four USB (Universal
Serial Bus) connector, a PS/2 keyboard, mouse and 1394a connectors. One
AGP slot, five PCI local bus slots and one communication and networking
riser (CNR) slot provide expandability for add-on peripheral cards.

CChhoooossiinngg aa CCoommppuutteerr CCaassee
There are many types of computer cases on the market. The mainboard complies with the specifications for the ATX system case. Some features on the
mainboard are implemented by cabling connectors on the mainboard to indicators and switches on the system case. Ensure that your case supports all
the features required. The mainboard can support one or two floppy diskette
drives and four enhanced IDE drives. Ensure that your case has sufficient
power and space for all the drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that
the I/O template in the case matches the I/O ports installed on the rear edge
of the mainboard.
This mainboard has an ATX form factor of 305 mm x 244 mm. Choose a case
that accommodates this form factor.
This mainboard uses Award BIOS t hat enables users to configure many system features including the fol l owing:
• Power management
• Wake-up alarm s
• CPU parameters
• CPU and memory timing
The firmware can also be used to set parameters for different

Follow these safety precautions when installing the mainboard:
• W ear a grounding strap attached to a grounded device to avoid
damage from static electricity.
• Discharge static electricity by touching the metal case of a safely
grounded object before working on the mainboard.
• Leave components in the static-proof bags they came in.
• Hold all circuit boards by the edges. Do not bend circuit boards.

This section explains how to set jumpers for correct configuration of the mainboard.
Setting Jumpers
Use the mainboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the
jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPE N.

Power / Sleep / Message Waiting LED
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a momentary-contact switch that is normally open. When the switch is closed, the board
resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
time requirement is due to internal debounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply recognizes another on/off signal.

Installing the Processor
Caution: When install i ng a CP U heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of the surface-mount resistors
with the clip of the cooling fan. If the cli p of the cool ing fan scrapes
across the mainboard, you may cause serious damage to the mainboard
or its components.
On most mainboards, there are small surface-mount resi stors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-l i t work area so that you can
clearly see the mainboard and processor socket.
Before installing the Processor
This mainboard automatically determines the CPU clock frequency and system bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can permanently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.
This mainboard has a Socket 462 processor socket. When choosing a p rocessor, consider the performance requirements of the system. Performance is
based on the processor design, the clock speed and system bus frequency of
the processor, and the quantity of internal cache memory and external cache
memory.

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the CPU:
1. Pull the CPU socket locking lever away from the socket to unhook it and rai se the
locking lever to the upright position.
2. Match the corner on the CPU marked with an arrow with pin A-1 on the CPU
socket (the corner with the pi nhol e not i ceably missing). I nsert the processor into
the socket. Do not us e force.
3. Swing the locking lever down and hook it under the latch on the edge of the
socket.
4. Apply thermal grease to the top of the CPU.
5. Lower the CPU cooling fan/heatsink assembl y ont o t he CPU
6. Secure the two retention clips
on either side of the
fan/heatsink unit onto the
Socket 462 base.
