Hardware Setup JP2, JP6: Power Supply Selection Jumpers These two jumpers let you select either the AT or the ATX power supply. Use only one power supply at a time on this mainboard. AT Power Supply (default) ATX Power Supply JP37: DIMM Voltage Jumper There are two kinds of DIMM voltages in the marketÑ3.3V and 5VÑ...
Hardware Setup JP9, JP10: SDRAM Frequency Selection Jumper SDRAM frequency is the same as CPU frequency (60/66/75/83/100 MHz) (defautl) SDRAM frequency is the same as AGP frequency (66 MHz) SDRAM is running at CPU frequency JP10 (defautl) SDRAM is running at AGP frequency Note: 1.
Hardware Setup CPU Type Configuration SW1 and JP30 are the only switchs/jumpers that you need to set for your CPU on this mainboard. Make sure that you know the type of CPU that you are installing and refer to the proper settings which are listed below. If you have a higher frequency CPU then the one listed below, see the ÒQuick Installation GuideÓ...
Hardware Setup Memory Configuration The mainboard supports two strips of 72-pin 5V FPM/EDO DRAM (SIMM) from 4 to 32MB and two strips of 168-pin 3.3V/5V Unbuffered DIMM modules from 8 to 128MB. The mainboard requires SIMM modules of at least 70ns access time. You can install memory in any combination without having to rely on a memory configuration table.
Hardware Setup Multi I/O Port Addresses Default settings for multi-I/O port addresses are shown in the table below. Port I/O Address Status LPT1* 378H ECP + EPP COM1 3F8H COM2 2F8H * If default I/O port addresses conflict with other I/O cards (e.g. sound cards or I/O cards), you must adjust one of the I/O addresses to avoid address conflict.
Hardware Setup HD LED – IDE Device LED Connector Attach a 2-pin IDE drive LED cable to this connector. The LED lights when an IDE device is active. KB_LOCK – Keylock & Power LED Connector It is a 5-pin connector for a lock that may be installed on the system case for enabling or disabling the keyboard.
Hardware Setup JP44 – Wake-On-LAN (WOL) Header Attach a 3-pin connector from the LAN card which supports the Wake- On-LAN (WOL) function. This function lets users wake up the connected computer through the LAN card. (The cable should be included with the LAN card.) JP44 Pin Assignment SENSOR PS1 –...
Hardware Setup AT PWR (CN1)– AT Power Supply Connectors The mainboard requires a power supply with at least 200 watts and a Òpower goodÓ signal. AT PW has two 6-pin male header connectors. Plug the dual connectors from the power directly onto the board connector while making sure the black leads are in the center.
Hardware Setup JP12 – CPU Cooling Fan Connector Attach a 3-pin CPU cooling fan cable to this connector. Make sure the pin assignment of the fan matches this connector or you may damage the system. This fan will stop when the system is into the suspend mode, if you enable the Suspend Mode in the BIOS setup.
3 BIOS Setup The mainboardÕs BIOS setup program is the ROM PCI/ISA BIOS from Award Software Inc. Enter the Award BIOS programÕs Main Menu as follows: 1. Turn on or reboot the system. After a series of diagnostic checks, you are asked to press DEL to enter Setup. 2.
