INTRODUCTION

The MS-6340 Micro-ATX VA mainboard is a high-performance
computer mainboard based on VIA® KT133 chipset. The MS-6340 is
designed for the AMD® Socket processor for inexpensive business/
personal desktop markets.

The KT133 chipset consists of the VT8363 system controller (552
pin BGA) and the VT82C686A PCI to ISA bridge (352 pin BGA). The system
controller provides superior performance between the CPU, DRAM, AGP
bus, and PCI bus with pipelined burst, and concurrent operation.

The VT82C686A integrates all system control functions such as
ACPI (Advances Configuration and Power Interface). The ACPI provides
more Energy Saving Features for the OSPM (OS Direct Power Management)
function. The VT82C686A chipset also improves the IDE transfer rate by
supporting Ultra DMA-33/66 IDE that transfers data at the rate 33/66MB sec.

This mainboard which supports KT133 chipset coupled with
VT8363 and VT82C686A is ideal for high performance, high quality, high
energy efficient and high integration desktop AGP/PCI/ISA computer
systems.

HARDWARE INSTALLATION

2.1 Central Processing Unit: CPU

The mainboard operates with AMD® DuronTM/Athlon processor. The
mainboard uses a CPU socket called Socket 462 for easy CPU installation.
The CPU should always have a Heat Sink and a cooling fan attached to
prevent overheating.

3. Press the lever down to
complete the installation.

2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

from the socket. Then, raise
the lever up to a 90-degree
angle.

2.1-1 CPU Installation Procedures

CHAPTER 2 HARDWARE INSTALLATION

2-2

The mainboard CPU Bus Frequency can be set through BIOS setup.

If CPU Clock = 100MHz

Core/Bus ratio = 7

then CPU core speed = Host Clock x Core/Bus ratio

= 700MHz

2.1-3 Fan Power Connectors: C_FAN1/S_FAN1

These connectors support system cooling fan with + 12V. It supports three
pin head connector. When connecting the wire to the connector, always
take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.

For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.

Note: Always consult vendor for proper CPU cooling fan.

program writes to this memory area, a system error may result. The settings
are: Enabled and Disabled.

Video RAM Cacheable

Select Enabled allows caching of the video BIOS , resulting in
better system performance. However, if any program writes to this memory
area, a system error may result. The settings are: Enabled and Disabled.

Primary/Secondary Master/Slave PIO

The four IDE PIO (Programmed Input/Output) fields let you set a PIO
mode (0-4) for each of the four IDE devices that the onboard IDE interface
supports. Modes 0 through 4 provide successively increased performance.
In Auto mode, the system automatically determines the best mode for each
device. The settings are: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.

Primary/Secondary Master/Slave UDMA

Ultra DMA/33 implementation is possible only if your IDE hard drive
supports it and the operating environment includes a DMA driver (Windows
95 OSR2 or a third-party IDE bus master driver). If your hard drive and your
system software both support Ultra DMA/33 and Ultra DMA/66, select
Auto to enable BIOS support. The settings are: Auto, Disabled.

Init Display First

This item allows you to decide to activate whether PCI Slot or AGP
Slot. The settings are: PCI Slot, AGP Slot.

IDE HDD Block Mode

Block mode is also called block transfer, multiple commands, or
multiple sector read/write. If your IDE hard drive supports block mode (most
new drives do), select Enabled for automatic detection of the optimal number
of block read/writes per sector the drive can support. The settings are:
Enabled, Disabled.

Onboard FDD Controller

Select Enabled if your system has a floppy disk controller (FDD)
installed on the system board and you wish to use it. If you install add-on
FDC or the system has no floppy drive, select Disabled in this field.
The settings are: Enabled and Disabled.

Onboard Serial Port 1/Port 2

This item allows you to enable the TX, RX inverting which depends
on different H/W requirement. This field is not recommended to change its
default setting for avoiding any error in your system.

Onboard Parallel Port

There is a built-in parallel port on the on-board Super I/O chipset
that provides Standard, ECP, and EPP features. It has the following options:

Onboard Parallel Mode

SPP : Standard Parallel Port

EPP : Enhanced Parallel Port

ECP : Extended Capability Port

To operate the onboard parallel port as Standard Parallel Port only,
choose “SPP.” To operate the onboard parallel port in the ECP and SPP
modes simultaneously, choose “ECP/SPP.” By choosing “ECP”, the
onboard parallel port will operate in ECP mode only. Choosing “ECP/EPP”
will allow the onboard parallel port to support both the ECP and EPP modes
simultaneously. The ECP mode has to use the DMA channel, so choose the
onboard parallel port with the ECP feature. After selecting it, the following
message will appear: “ECP Mode Use DMA” At this time the user can
choose between DMA channels 3 or 1. The onboard parallel port is EPP
Spec. compliant, so after the user chooses the onboard parallel port with the
EPP function, the following message will be displayed on the screen: “EPP
Mode Select.” At this time either EPP 1.7 spec. or EPP 1.9 spec. can be
chosen.

ECP Mode Use DMA

This section describes configuring the PCI bus system. PCI, or Personal
Computer Interconnect, is a system which allows I/O devices to operate at

speeds nearing the speed the CPU itself uses when communicating with its
own special components. This section covers some very technical items
and it is strongly recommended that only experienced users should make
any changes to the default settings.

PnP OS Installed

When set to YES, BIOS will only initialize the PnP cards used for
booting (VGA, IDE, SCSI). The rest of the cards will be initialized by the PnP
operating system like Windows® 95 or 98. When set to NO, BIOS will
initialize all the PnP cards. So, for non-PnP operating system (DOS,

ENTER PASSWORD:

Type the password, up to eight characters in length, and press <Enter>. The
password typed now will clear any previously entered password from CMOS
memory. You will be asked to confirm the password. Type the password again
and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.

To disable a password, just press <Enter> when you are prompted to enter the
password. A message will confirm the password will be disabled. Once the
password is disabled, the system will boot and you can enter Setup freely.

PASSWORD DISABLED.

When a password has been enabled, you will be prompted to enter it every
time you try to enter Setup. This prevents an unauthorized person from chang­ing any part of your system configuration.

Additionally, when a password is enabled, you can also require the BIOS to
request a password every time your system is rebooted. This would prevent
unauthorized use of your computer.

CHAPTER 3 AWARD® BIOS SETUP
