[. . . ] Installing Thermal Sensor The Thermal Sensor Connector (CN12 & CN1) provides you to use the thermal sensor to detect the CPU temperature of the components on the motherboard. 5. SW1 Setting CPU FSB Frequency & Ratio When you are using the Intel® engineer sample CPU with DX34/DX34Plus, the SW1 allows you select the CPU ratio from 2x to 9. 5 x. You can adjust the SW1 to get the correct CPU working ratio and frequency. ON OFF GND Sensor 1 SW1 Warning: We strongly recommend you do not overclocking your CPU and system for get more system reliability. 4. SW3 Select CPU Type Bit1 This motherboard supports DUAL processors for Intel PentiumII / Pentium!!!, and Celeron CPU (applied to PPGA package only, must lower than 300MHz). [. . . ] Connecting 68-pin Ultra3 SCSI Cable (DX34 Plus) The DX34Plus provides two 68-pin Ultra Wide/Ultra 2/3 SCSI connectors for 16-bit or 16-bit differential SCSI devices. 12. CD-IN & FAX-Voice Connector (Applied to DX34) If you have installed the CD-ROM drive in the system, the CD-In Connector (CN19) can be connected to audio output connector of internal CD-ROM drive. This FAX-VOICE connector (CN21) can let the fax sound of Modem device speak out from external speaker by connected . to internal Modem card. 68-pin SCSI Ultra3 Connectors Connector CD-IN FAX-Voice Pin1 Left Pin2 GND Pin3 GND GND Pin4 Right Phone MIC-IN GND 11. Connecting Front Panel Connector Attaching such as power LED, reset switch, power switch connector, etc. . . . corresponding pins. ATX Power Switch Power LED Chassis Intrusion Switch 13. Connecting SCSI LED Connector to The 4-pin SCSI LED connector can be connected to the SCSI hard disk control card activity LED connector. Read or write activity by devices connected to the SCSI card will cause the LED lighting up. 1 2 21 22 CN23 HDD LED Reset Switch + + + + - +5V GND PWR LED +5VSB 1 2 GND +5V HDD LED HDD LED +5V CN24 RST S/W INT S/W 21 22 GND GND 14. Speaker There is one jumper cap over pin1 and pin2 of JP4 for internal buzzer. If you want to use external case-mounted speaker instead of internal buzzer, please remove jumper cap to short pin2 and pin3. 16. Power-On and Load BIOS Setup After you finish the setting of jumpers and connect correct cables. Power on and enter the BIOS Setup, press <Del> during POST (Power On Self Test). Choose "Load Default Setting" for recommended optimal performance. Del 1 1 1 JP4 Buzzer (Default) Speaker Warning: Please avoid of using "Load Turbo Defaults", unless you are sure your system components (CPU, DRAM, HDD, etc. ) are good enough for turbo setting. 15. SCSI Channel Terminator Control (DX34 Plus only) The JP3/JP3X allows you to enable or disable the on-board SCSI Channel A and B terminator control function. The SCSI Channel A is controlled by JP3; the Channel B is controlled by JP3X. 17. Installing Onboard Sound Driver This motherboard comes with an AD 1885 AC97 CODEC. You can find the audio driver from the Bonus Pack CD disc autorun menu. JP3 JP3X 1 1 ON (Default) OFF Part Number and Serial Number If you encounter any trouble to boot you system, follow the procedures accordingly to resolve the problem. You can find this bar code label on the outside packing, on ISA/CPU slot or on component side of PCB. For example: Start Turn off the power and unplug the AC power cable, then remove all of the addon cards and cables, including VGA, IDE, FDD, COM1, COM2 and Printer. Make sure if the jumper settings for CPU and DRAMs are correct. Part No. Serial No. Clear CMOS. Install the VGA card. Then connect your monitor and keyboard. Part No. Serial No. P/N: 91. 88110. 201 is part number, S/N: 91949378KN73 is serial number. Turn on the power, and check if the power supply and CPU fan work properly. No The problem was probably caused by power supply or motherboard failure.
