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. Since 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. 3.5. CPU SPEED SETUP The system bus speed can be set to 66.6MHz or 100MHz form the jumper (JP5). 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. Set system speed to 66MHz: JP5 pin 1-2 short will cause system always run at 66 MHz FSB (Front Side Bus). JP5 1 2 Set system speed to 100MHz: JP5 all pins open will cause system always run at 100MHz FSB. JP5 1 2 Set system speed to Auto: JP5 pin 2-3 short will detect system speed 66/100MHz FSB automatically. JP5 3-5 6BXS 1 2 DIP SWITCH (SW) FREQ. RATIO EXT.CLK. MHz INT.CLK.

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 REALTIME 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. 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. 3-6 Hardware Installation 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 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 PWR of mainboard in 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.
