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 6VMA mainboard.
•Universal Retention Mechanism & Attach Mount
•USER'S MANUAL for mainboard.
•Cable set for IDE, Floppy devices.
•CD or diskette for Mainboard ¡BSound Utility.
The mainboard contains sensitive electric components, which can be easily
damaged by static electricity, so the mainboard 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 mainboard 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 mainboard 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 mainboard can be installed with 16 / 32 / 64 / 128 / 256 MB 168 pins DIMM
module DRAM, and the DRAM speed must be 67~100 MHz for SDRAM. The
DRAM memory system on mainboard consists of bank 0 , bank 1, bank 2.
Since 168 pins DIMM module is 64 bits width, using 1 PCS which can match a
64 bits system. The total memory size is 16MB ~ 768MB / 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 couldn't be inserted into socket completely.
3.5. CPU SPEED SETUP
The default system bus speed is 66 / 100MHz (SW2). The user can change the
DIP SWITCH (SW1) selection to set up the CPU speed for 233 - 633MHz
processor. The CPU speed must match with the frequency RATIO. It will cause
system hanging up if the frequency RATIO is higher than CPU's.

M 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 mainboard.
M We don’t recommend you to setup your system speed to 75, 83, 112,
or 133MHz because these frequencies are not the standard
specifications for CPU, Chipset and most of the peripherals.
Whether your system can run under 75, 83, 112 or 133MHz properly
will depend on your hardware configurations: CPU, SDRAM, Cards,
etc.

Hardware Installation

3.6. CMOS RTC & ISA CFG CMOS SRAM
The mainboard contains 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 when it has consumed.
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
TheRESETswitch onpanelprovides userswithHARDWARE RESETfunction.
The system will do a cold start after the RESET switch is press and released by
user. The RESET switch is a 2 PINS connector and should be installed to RES
on mainboard.
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 LED of mainboard in correct direction.
3.10. IDE & ATAPI DEVICE INSTALLATION
There are two-Enhanced PCI IDE ports (IDE1, IDE2)onboard, whichfollowing
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

6VMA
3-10
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 three 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.
