[. . . ] Tip: There are many useful information in our homepage, such as jumper settings, latest BIOS, drivers, and more FAQs.

Check all jumper settings according to section 2. 2 "Jumpers". [. . . ] 3. Set DRAM timing to 70ns and disable all enhanced chipset features in BIOS. If you are using an old SIMM or a remarked SIMM, you may need to manually slow down the DRAM timing and disable the chipset features. Some add-on cards, drivers or applications may not be compatible with these functions. Disable the external cache (2nd level cache) in chapter 3 "Advanced CMOS Setup" (AMI) or "BIOS Features Setup" (AWARD). If the system works fine, your cache module or onboard PBSRAM may be malfunction. Enter BIOS and set the HDD "Block" and "32-bit" mode parameters to OFF. Refer to Chapter 3 "Standard CMOS Setup" (AMI) or "Integrated Peripherals" (AWARD) for details. Turn off the power and remove all add-on cards, connectors and SIMMs from your mainboard. Then reinstall the VGA card, two SIMMs and connect only one hard disk to the end-most connector of the IDE cable. The IDE cable length must not exceed 46cm (18inches), refer to section 2. 3 "Connectors". If the system functions properly, reinstall the add-on cards one by one. This will help you find out which card or device is causing the problem. Be sure to connect the 2nd IDE device (HDD/CD-ROM) to the primary channel slave mode. 4. If your CPU bus frequency is 66MHz, set the CPU external/bus frequency to 60MHz, but leave the CPU core/bus frequency ratio unchanged. Normally, CPU with 66MHz bus frequency works properly at slower speed, e. g. , 60MHz. This will help you identify if the CPU is remarked or if the mainboard or add-on card is unstable at 66MHz. Keyboard, Mouse, Printer or Floppy is not working properly. 1. Make sure that pin 1 of the cable is connected to pin1 of the connector. If possible, use another peripheral to double check if the mainboard or the cable is defective. 2. [. . . ] Write down your configuration and error symptoms as detailed as possible.
