1.6 What is AGP ?
The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI
bridge device that supports an AGP port. The main purpose of the AGP port
is to provide fast access to system memory.
The AGP port can be used either as fast PCI port (32-bits at 66MHz vs. 32-
bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue,
and side band addressing. When the 2x-data rate is used the port can
transmit data at 533MB/sec (66.6*2*4). The read-queue can be used to
pipeline reads –removing the effects of the reads-latency. Side band
addressing can be used to transmit the data address on a separate line in
order to speed up the transaction.

3. HARDWARE INSTALLATION
3.1. UNPACKING
The main board package should contain the following:
•The 6VA main board.
•Universal Retention Mechanism & Attach Mount
•USER'S MANUAL for main board.
•Cable set for IDE, Floppy & I/O devices.
•CD for main board Utilities.
The main board contains sensitive electric components, which can be easily
damaged by static electricity, so the main board should be left in its original
packing until it is installed.
Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti static wristband, grounded at the
same point as the anti-static mat.
Inspect the main board carton for obvious damage. Shipping and handling
may cause damage to your board. Be sure there are no shipping and
handling damages on the board before proceeding.
After opening the main board carton, extract the system board and place it
only on a grounded anti-static surface component side up. Again inspect the
board for damage. Press down on all of the socket IC's to make sure that
they are properly seated. Do this only on with the board placed on a firm flat
surface.
M DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED.

3.4. DRAM INSTALLATION
The main board can be installed with 16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM. When system bus speed is set to 100MHz, 100MHz
SDRAM is required. The DRAM memory system on main board consists of
bank 0, 1, 2 & bank 3.
Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM
module may match a 64 bits system. The total memory size is 16 MB ~ 1
GB SDRAM. The DRAM installation position refer to Figure 3.1, and notice
the Pin 1 of DIMM module must match with the Pin 1 of DIMM socket. Insert
the DRAM DIMM module into the DIMM socket at Vertical angle. If there is a
wrong direction of Pin 1, the DRAM DIMM module could not be inserted into
socket completely.
3.5. CPU SPEED SETUP
The system bus speed can be set to 66.6MHz or 100MHz form the jumper
(JP8). The user can change the DIP SWITCH selection to set up the CPU
speed for different processors. The CPU speed must match with the
frequency RATIO and Front Side Bus (FSB) speed. It will cause system
hanging up if the frequency RATIO and FSB Speed do not match with the
CPU.
Set system speed to 66MHz: JP8 pin 1-2 short will cause system
always run at 66 MHz FSB (Front Side Bus).
Set system speed to 100MHz: JP8 all pins open will cause system
always run at 100MHz FSB.

3.6. CMOS RTC & ISA CFG CMOS SRAM
There're RTC & CMOS SRAM on board; they have a power supply from
external battery to keep the DATA inviolate & effective. The RTC is a REAL-
TIME CLOCK device, which provides the DATE & TIME to system. The
CMOS SRAM is used for keeping the information of system configuration, so
the system can automatically boot OS every time. Since the lifetime of
internal battery is 5 years, the user can change a new Battery to replace old
one after it cannot work.
MDanger of explosion if battery is incorrectly replaced.
MReplace only with the same or equivalent type recommended by the
manufacturer.
MDispose of used batteries according to the manufacturer’s instructions.
3.7. SPEAKER CONNECTOR INSTALLATION
There is a speaker in AT system for sound purpose. The 4 -Pins connector
SPK is used to connect speaker. Anode connects +, Cathode connects −.
3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION
The RESET switch on panel provides users with HARDWARE RESET
function. The system will do a cold start after the RESET button is pressed
and released by user. The RESET switch is a 2 PIN connector and should be
installed to RST on main board.
3.9. POWER LED CONNECTOR INSTALLATION
System has power LED lamp on the panel of case. The power LED will light
on/off or flash to indicate which step on the system. The connector should be
connected to PWR of main board in correct direction.

Hardware Installation

3.10. IDE & ATAPI DEVICE INSTALLATION
There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which
following ATAPI standard SPEC. Any one IDE port can connected to two
ATAPI devices (IDE Hard Disk, CD-ROM & Tape Driver), so total four ATAPI
devices can exist in a system. The HD is the active LED port for ATAPI
devices.
3.11. PERIPHERAL DEVICE INSTALLATION
After the I/O device installation and jumpers setup, the main board can be
mounted into the case and fixed by screw. To complete the main board
installation, the peripheral device could be installed now. The basic system
needs a display interface card. If the PCI - Bus device is to be installed in the
system, any one of four PCI - Bus slots can be used.
3.12. KEYBOARD & PS/2 MOUSE INSTALLATION
The main board supports PS/2 Mouse. The BIOS will auto detect whether the
PS/2 Mouse is installed or not & assign IRQ12 for PS/2 Mouse port if it is
installed. After installing the peripheral device, the user should check
everything again, and prepare to power-on the system.

4. BIOS CONFIGURATION
Award's BIOS ROM has a built-in Setup program that allows users to modify
the basic system configuration. This type of information is stored in battery-
backed CMOS SRAM so that it retains the Setup information when the power
is turned off.
4.1. ENTERING SETUP
Power ON the computer and press <Del> immediately will allow you to enter
Setup. If the message disappears before you respond and you still wish to
enter Setup, restart the system to try again by turning it OFF then ON or
pressing the "RESET" bottom on the system case. You may also restart by
simultaneously press <Ctrl>, <Alt>, and <Del> keys.
