Introduction
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 mainboard package should contain the following:
·
·
·
·
·
The 6EA main board.
The Retention Mechanism & Attach Mount
USER'S MANUAL for main board.
Cable set for IDE, Floppy & I/O devices.
CD for main board Utility. (Bus Master IDE Driver, Suspend to HD Utility,
LDCM, SIV, Patch 95)
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 8 / 16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM, and the DRAM speed must be 50 or 60 ns for EDO &
67MHz for SDRAM when system bus speed is set to 66MHz. The DRAM
memory system on main board consists of bank 0 and bank 1 .
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 8 MB ~ 256MB
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 form the jumper (JP2,JP3,JP4).
The user can change the DIP SWITCH (SW) 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.

The CPU is a sensitive electric component and it can be easily
damaged by static electricity, so users must keep it away from metal
surface when the CPU is installed onto main board.
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.
M Danger of explosion if battery is incorrectly replaced.
M Replace only with the same or equivalent type recommended by the
manufacturer.
M Dispose 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.
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 switch is pushed 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 a correct direction.
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 mainboard can be
mounted into the case and fixed by screw. To complete the mainboard
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 (J7). 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.
