  • Page 76 Q: All I get are beep codes. What do they mean? A: Fatal errors, which halt the boot process, are communicated through a series of audible beeps.

  • Page 77: Video Issues

    Q: Does my operating system support AGP? A: Currently, only Windows 98 and Windows NT 5.0 will have built-in support for AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver from Intel. Please check with your graphics vendor for more details. http://www.tyan.com...

  • Page 78: Cpu Issues

    IDT CPUs are not supported in dual mode. Q: Can I overclock my CPU? A: Overclocking your CPU is not recommended by TYAN. Because TYAN does not recommend this, we are not able to provide technical support to those who are overclocking their CPUs. Overclocking your CPU may cause damage to your system board and/or shorten the life expectancy of your CPU.

  • Page 79: Memory Issues

    A: It isn’t a good idea to mix brands, types, and speeds of RAM because all Tyan motherboards are produced with performance in mind. When we talk about performance, it goes hand in hand with tolerances which must be met in order to reach the performance levels expected of high quality peripher- als.

  • Page 81: Bios Issues

    Tyan motherboards use either AMI or Award BIOS. The BIOS version can be found at bootup just below the left hand corner logo. Ignore all version numbers that do not start with “TYN”. Tyan BIOS versions begin at startup with the following line: TYN [motherboard model] Vx.xx MM/DD/YY...

  • Page 83 3. If you have replaced the motherboard and the problem still persists, it’s probably not the motherboard at fault. There is a very, very slim chance that two consecutive boards will be bad..however, if it’s exhibiting the same symptoms, check with your peripheral vendors for possible conflicts and compatibility issues. http://www.tyan.com...
