III. INSTALLATION 3. Central Processing Unit (CPU) The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible with ZIF Socket 5 processors. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case then purchase a fan before you turn on your system. Apply thermal jelly to the CPU top and then install the fan onto the CPU.
III. INSTALLATION 4. Expansion Cards WARNING! Make sure that you unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards. Expansion Card Installation Procedure: III. INSTALLATION (Expansion Cards) 1. Read your expansion card documentation on any hardware and software settings that may be required to setup your specific card. 2. Set any necessary jumpers on your expansion card. 3.
III. INSTALLATION To simplify this process this motherboard has complied with the Plug and Play (PNP) specification which was developed to allow automatic system configuration whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available. If the system has both Legacy and PNP ISA cards installed, IRQs are assigned to PNP cards from those not used by Legacy cards.
III. INSTALLATION 5. External Connectors WARNING! Some pins are used for connectors or power sources. These are clearly separated from jumpers in “Map of the Motherboard.” Placing jumper caps over these will cause damage to your motherboard. IMPORTANT: Ribbon cables should always be connected with the red stripe on the Pin 1 side of the connector. The four corners of the connectors are labeled on the motherboard. Pin 1 is the side closest to the power connector on hard drives and floppy drives.
III. INSTALLATION 3. Parallel Printer Connector (25-pin Female) You can enable the parallel port and choose the IRQ through “Onboard Parallel Port” in Chipset Features Setup of the BIOS SOFTWARE. NOTE: Serial printers must be connected to the serial port. Parallel (Printer) Port (25-pin Female) III. INSTALLATION (Connectors) 4. Serial Port COM1 and COM2 Connectors (Two 9-pin Male) The two serial ports can be used for pointing devices or other serial devices.
III. INSTALLATION 6. Audio Port Connectors (Three 1/8” Female) (with optional onboard Audio) Line Out can be connected to headphones or preferably powered speakers. Line In allows tape players or other audio sources to be recorded by your computer or played through the Line Out. Mic allows microphones to be connected for inputing voice. Line Out Line In Mic 1/8" Stereo Audio Connectors III. INSTALLATION (Connectors) 7.
III. INSTALLATION 9. Primary / Secondary IDE connectors (Two 40-1pin IDE) These connectors support the provided IDE hard disk ribbon cable. After connecting the single end to the board, connect the two plugs at the other end to your hard disk(s). If you install two hard disks, you must configure the second drive to Slave mode by setting its jumper accordingly. Please refer to the documentation of your hard disk for the jumper settings.
III. INSTALLATION 11. Chassis , CPU , & Power Supply Fan Connectors (3-pin FANPWR) These connectors support cooling fans of 500mAMP (6WATT) or less. Orientate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground.
III. INSTALLATION 13. IrDA / Fast IR-Compliant infrared module connector (5-pin IR) This connector supports the optional wireless transmitting and receiving infrared module. This module mounts to a small opening on system cases that support this feature. You must also configure the setting through “UART2 Use Infrared” in Chipset Features Setup to select whether UART2 is directed for use with COM2 or IrDA.
III. INSTALLATION 15. Onboard Digital Audio Control (VOLCTL) (with optional onboard Audio) This jumper allows you to adjust the audio volume digitally using case mounted momentary buttons.

IV. BIOS SOFTWARE Support Software FILELIST.TXT - View this file to see the files included in the support software. PFLASH.EXE - This is the Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM chip on the motherboard. To determine the BIOS version, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Larger numbers represent a newer BIOS file.
IV. BIOS SOFTWARE Main Menu 1. Save Current BIOS To File This option allows you to copy the contents of the flash memory onto a floppy disk. This gives you a backup copy of the original motherboard BIOS in case you need to reinstall it. Create a bootable DOS diskette without AUTOEXEC.BAT and CONFIG.SYS and save both PFLASH.EXE and the BIOS file(s) to it. Note: BIOS FEATURES SETUP Boot Sequence needs to be set to A first in order to boot from your disk drive A. 2.
IV. BIOS SOFTWARE Managing and Updating Your Motherboard’s BIOS Upon First Use of the Computer System 1. Create a bootable system floppy diskette by typing [FORMAT A:/S] from the DOS prompt without creating “AUTOEXEC.BAT” and “CONFIG.SYS” files. 2. Copy PFLASH.EXE to your new diskette. 3. Run PFLASH.EXE from your new diskette and select option 1 “Save Current BIOS to File.” Enter the “Current BIOS Revision:” for the file name.
IV. BIOS SOFTWARE 6. BIOS Setup The motherboard supports two programmable Flash ROM chips: 5 Volt and 12 Volt. Either of these memory chips can be updated when BIOS upgrades are released. Use the Flash Memory Writer utility to download the new BIOS file into the ROM chip as described in detail in this section. All computer motherboards provide a Setup utility program for specifying the system configuration and settings.
IV. BIOS SOFTWARE Load Defaults The Load BIOS Defaults option loads the minimum settings for troubleshooting. Load Setup Defaults, on the other hand, is for loading optimized defaults for regular use. Choosing defaults at this level will modify all applicable settings. A section at the bottom of the preceding screen displays the control keys for this screen. Take note of these keys and their respective uses.
IV. BIOS SOFTWARE Time To set the time, highlight the “Time” field and then press either / or <+>/<–> to set the current time. Follow the hour, minute and second format. Valid values for hour, minute and second are: (Hour: (00 to 23), Minute: (00 to 59), Second: (00 to 59). If you do not want to modify the current time, press three times to go to Hard Disks. NOTE: You can bypass the date and time prompts by creating an AUTOEXEC.BAT file.
IV. BIOS SOFTWARE Auto detection of hard disks on bootup For each field: Primary Master, Primary Slave, Secondary Master, and Secondary Slave, you can select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE hard disk during bootup. This will allow you to change your hard disks (with the power off) and then power on without having to reconfigure your hard disk type.
