Jumper Settings for CMOS Clear Jumper JP13 CMOS Clear Select If, for some reason, the CMOS becomes corrupted, the system can be reconfigured with the default values stored in the ROM BIOS. To load the default values, power off your system and set JP13 pins 2 and 3 to On. Power on your system. After you boot up an operating system, turn your system off again. Set JP13 back to its default setting, pins 1 and 2 On.
After setting these jumpers, the CPU will multiply the external bus clock by the frequency ratio to become the internal clock speed. Internal clock speed is the commonly used speed of the processors in the market and is the actual operating clock of the processor. external bus clock x frequency ratio = internal clock speed Jumper JP6 is used to set the cache burst mode of your processor. Refer to the following pages and set this jumper accordingly.

Chapter 4 Troubleshooting Checklist This chapter of the manual is designed to help you with problems that you may encounter with your personal computer. To efficiently troubleshoot your system, treat each problem individually. This is to ensure an accurate diagnosis of the problem in case a problem has multiple causes. Some of the most common things to check when you encounter problems while using your system are listed below. 1. The power switch of each peripheral device is turned on. 2.
The picture seems to be constantly moving. 1. The monitor has lost its vertical sync. Adjust the monitor’s vertical sync. 2. Move away any objects, such as another monitor, speakers or fan, that may be creating a magnetic field around the display. The screen seems to be constantly wavering. 1. If the monitor is close to another monitor, the adjacent monitor may need to be turned off. Fluorescent lights adjacent to the monitor may also cause screen wavering.
Hard Drive Hard disk failure. 1. Make sure the correct drive type for the hard disk drive has been entered in the BIOS. 2. If the system is configured with two hard drives, make sure the bootable (first) hard drive is configured as Master and the second hard drive is configured as Slave. Excessively long formatting period. 1. If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem (or you have a very large hard drive - but this will be normal).
2. Verify that the device is plugged into the correct serial port on the rear of the computer. 3. Verify that the attached serial device works by attaching it to a serial port that is working and configured correctly. If the serial device does not work, either the cable or the serial device has a problem. If the serial device works, the problem may be due to the onboard I/O or the address setting. 4. Make sure the COM settings and I/O address are configured correctly.
