Taiwan http://www.aopen.com.tw http://www.aopen-usa.com http://www.aopenamerica.com Europe http://www.aopen.nl No display Check all jumper settings according to section 2.2 "Jumpers". Make sure that you have set the proper jumpers especially those for CPU frequency, core and IO voltage select functions.
  • Page 93 Troubleshooting the problem is your add-on cards or peripheral. try to reinstall the add-on cards one by one to find out which card is causing the problem. Check the monitor and VGA cable. Press the <Num Lock> key to enable/disable the Num Lock function. If the Num Lock LED works properly, this indicates that your CPU, SIMM and BIOS bootup sequence are properly functioning.
  • Page 94 Troubleshooting 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.
  • Page 95 Refer to Chapter 3 "Advanced CMOS Setup" section. Some applications has trouble at higher system speed. Visit our WWW home page, (address http://www.aopen.com.tw), check the FAQ area (frequently asked question) and download the latest BIOS, try again with the latest BIOS.
