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 further speed the transaction.

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. MDO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED. You are now ready to install your mainboard. The mounting hole pattern on the mainboard matches the ATX system board. It is assumed that the chassis is designed for a standard ATX mainboard mounting. Place the chassis on the anti-static mat and remove the cover. Take the clips, stand-off and screws for mounting the system board, and keep them

DRAM INSTALLATION The mainboard 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 & 67~100 MHz for SDRAM. The DRAM memory system on mainboard consists of bank 0, 1, 2 & bank 3. Because the 168 pins DIMM module is 64 bits width, using 1 PCS which can match a 64 bits system. The total memory size is 8 MB ~ 1 GB EDO or 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.

The system's speed is fixed to 66.6MHz. The user can change the DIP SWITCH (SW) selection to set up the CPU speed for 200 - 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. DIP SWITCH (SW) 1 2 3 4 FREQ. RATIO JP10 EXT.CLK. MHz INT.CLK.

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. 1 2 3 1 2 3 1 2 3

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. Due to the life-time of Battery internal battery is 5 years, the user can change a new Battery to replace old one after it can not 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 always a speaker in AT system for sound purpose. The 4 - Pins connector J11 is used to connect speaker. The speaker can work well in both direction of connector when it is installed to the connector J11 on mainboard. 3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION The RESET switch on panel provides users with HARDWARE RESET function, which is almost the same as power-on/off. 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 J10 on mainboard. 3.9. POWER LED CONNECTOR INSTALLATION There are system power LED lamps on the panel of case. The power LED will light on when system is powered-on, which is connected to a 3 PIN connector. The connector should be connected to JP7 of mainboard in correct direction.

There are two Enhance PCI IDE ports 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 J7 is the active LED port for ATAPI device. 3.12. 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 five PCI - Bus slots can be used. 3.13. KEYBOARD & PS/2 MOUSE INSTALLATION The main board supports PS/2 connector type keyboard & Mouse (J3). The BIOS will auto detect whether the PS/2 Mouse is installed or nor & assign IRQ12 for Mouse port if which was installed. After installing the peripheral device, the user should check everything again, and prepare to power-on the system. 3.14. KEYBOARD SETTING FUNCTION After booting the O.S., there are some special functions used by keyboard as follows: "CTRL_ALT_DEL" − Pressing these keys simultaneously will cause system to Warm Start (Software Reset).
