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 92 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 93 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.

    BIOS revision Q: How can I identify version of the mainboard? A: The AOpen mainboard revision appears as Rev x.x on the PCB, near the PCI slot. For example, for AP5T revision 3.4, the revision number appears on the PCB as follows: AP5T revision 3.4...
  • Page 96 Frequently Asked Questions Q: What is FCC DoC (Declaration of Conformity)? A: The DoC is new certification standard of FCC regulations. This new standard allows DIY component (such as mainboard) to apply DoC label separately without a shielding of housing. The rule to test mainboard for DoC is to remove housing and test it with regulation 47 CFR 15.31.
  • Page 97 EPROM (Erasable Programmable ROM), if BIOS has to be upgraded, you need to remove EPROM from mainboard, clear by ultra-violet (UV) light, re- program, and then insert back.. AOpen mainboards use much easier Flash ROM, only Flash ROM programming utility is necessary, no need to open housing and change the BIOS ROM.
  • Page 98 This feature allows you to immediately resume to your original work without the long time waiting from bootup, entering Win95 and running Winword. The AX5TC with Intel TX chipset can support ACPI. Q: What is ATX Soft Power On/Off and Momentary Switch? A: The Soft Power On of the ATX specification means to provide a standby current for special circuit to wait for wakeup event when main power is off.
  • Page 99 Q: What is ADM (Advanced Desktop Manager)? A: This is a desktop client and server management software developed by AOpen. It is similar as Intel LDCM with some improvement. ADM is not only for corporate network management, it can also be used as system status monitoring utility, for example, CPU fan, thermal and system voltage monitoring.
  • Page 100 HP Open View) Remote File Transfer Q: Why the AOpen mainboards (MB) do not have cache module expansion slot? A: Faster CPU speed requires more difficult and complex MB timing design. Every trace and components delay must be taken into consideration. The...
