Pentium ® Processor PCI - ISA BUS MAINBOARD REV. [. . . ] Because the 168 pins DIMM module is 64 bits width, using 1 PCS which can match a 64 bits system. 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 3-5 5AA 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. 6. CPU INSTALLATION AND JUMPERS SETUP The system speed depends on the frequency of CLOCK GENERATOR. The user can change SW selection to set up the system speed to 66 / 75 /83 /95 100MHz for 3. 3V/2. 5V Pentium® Processor (133 / 166 / 200 MHz) ;MMX(166 / 200 / 233 MHZ) , AMD K6-(166 / 200 / 233 / 266 / 300 ; K6-2(266 / 300 / 333 / 350 / 366 / 380 / 400 / 450 / 475 / 500 / 550) ; K6-III(400 / 450 / 475 / 500 / 550) , Cyrix / IBM 6x86MX (PR166 / PR200 / PR233 / PR266 ) ; M¢ º - PR300 / PR333 / PR366 / PR400 ; IDT Winchip 2-(200 / 225 / 233 / 266 / 300) ; IDT Winchip 3-(266) ; RISE MP6-(266). The mainboard can use Pentium® Processor, MMX , AMD-K6, AMD-K6-2, AMD-K6III, Cyrix / IBM 6x86MX, Cyrix M¢ º Winchip 2, IDT Winchip 3, RISE MP6 , IDT CPU, and the CPU speed must match with the frequency of CLOCK GEN. It will cause system hanging up if the CLOCK GEN. 'S frequency is faster 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 When the user installs the CPU on socket, please notice that the PIN 1 of CPU is in the same corner as the PIN 1 of socket!M Before the CPU is installed, the mainboard must be placed on a flat plane in order to avoid being broken by the pressure of CPU installation.

CMOS RTC & ISA CFG CMOS SRAM Built-in Real Time Clock (RTC) With 256B CMOS SRAM in M5819. 3. 8. SPEAKER CONNECTOR INSTALLATION There is a speaker in AT system for sound purpose. The speaker can work well in both direction of connector when it is installed to the connector SPK on mainboard. 3. 9. ACPI LED CONNECTOR INSTALLATION This mainboard uses the existing power LED as ACPI LED . The ACPI LED will light on when system is power-on . The ACPI LED is off when the system is power-off. The ACPI LED will blink when system is in Green mode. This connector should be installed to ACPI LED jumper of the mainboard in correct direction. 3. 10. 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 RES on mainboard. 3. 11. GREEN FUNCTION INSTALLATION There is one jumper for the purpose of power saving, GN, to indicate the power saving function . PERIPHERAL DEVICE INSTALLATION After installation of the device and setup of the jumpers, the mainboard can be mounted into the case and fixed by screw.
