  1. What voltage is my memory?
    Consult your memory vendor or manufacturer for more information. In general, most memory is rated at 5 volts unless otherwise specified. If you are in doubt, try running your memory at 3v. Most 5v memory will run at a lower voltage without a problem.
     
  2. Basic Troubleshooting Guidelines (for Advanced Users)
    In order to verify that you have a marginal motherboard, follow this procedure.
     
    • Minimize your system to a "bare-bones" configuration.
      Remove all cards except for the video card (and SCSI if you are not using IDE) and boot up normally.  If you still get error messages in your current O/S, try booting to "safe" mode or to a standard configuration using generic drivers.  If the error goes away, it's a software issue and you should take it up with your software publisher.  Another option to try is to reset the CMOS to factory defaults.  The procedure will be found in your manual.
       
    • If your problem still persists after running it as a bare-bones system, disable all the enhancement features in the BIOS.
      An example would be to run your memory at its slowest setting, disable internal and external caches and turn off all BIOS shadowing.  Turn the options on one at a time until the system crashes.  After it crashes, you know what option is causing the problem so you can trace it back to a specific piece of hardware.  If you set your memory down to 70ns for instance and your problems go away, it's probably your memory causing the errors.  Try replacing that piece of hardware.
       
    • The basics of troubleshooting is simple.  Divide and conquer.
      Take one piece of the equation out at a time until the system stops doing what you don't want it to do.  This is THE EASIEST way to troubleshoot a problem.  In most cases, problems are not caused by the motherboard but rather by shared IRQs, improper installation, or user error.
       
    • If you have replaced the motherboard and the problem still persists, it's probably not the motherboard.
      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 compatiblity issues.
       
  3. I can't get my com ports to work.
    99% of the time, not being able to use a com port is a result of not using the supplied cables or the com ports are disabled in the BIOS.  To ensure  that the motherboard is recognizing and intializing the com ports, boot up the system and review the stat screen (the screen which pops up before it starts the O/S).  There you will find a section for I/O ports and if it is working properly, you should see the interupts the com ports are using.  (ie.. 2f8, 3e8... etc).  If the motherboard shows these as active, it's probably not a bad motherboard but rather a bad or incompatible cable, or you have a IRQ conflict with another communications device such as an internal modem.  Remember: you  MUST use the supplied cables in order to use the com ports on the motherboard!
     
  4. Where can I get a PS/2 Adapter?
    You should order a PS/2 adapter from the dealer from which you purchased your motherboard.  If they do not carry the item, they will be able to special order it for you.  Please visit a local reseller near you.
     
  5. Where can I get a USB Adapter?
    You should order a USB adapter from the dealer from which you purchased your motherboard.  If they do not carry the item, they will be able to special order it for you.  Please visit a local reseller near you.
     
  6. When I turn the computer on, the system displays strange CPU Speeds.
    The solution to this is to first check that you have the correct CPU jumper speed settings.  CPU Speed jumper settings can be found in our Product FAQ section.  Next, verify that your CPU is indeed what your ordered.  If you order a 150MHz CPU, make sure it's not a 120.  Overclocking may also play a role in strange CPU speed behavior.  NEVER overclock a CPU.  Overclocking may damage your CPU, system or both and will void your warranty.  If you have an older sound card, try moving the sound card to the last ISA slot closest to the edge of the board.  This will resolve most problems but if this fails, it's possible that there may be a problem with the motherboard's clock generator.  Return the motherboard to the dealer for repair or replacement.
     
  7. Which CPUs can I run in Dual Mode?
    The AMD and Intel CPUs can be run in Dual Mode at this time.  Cyrix and IBM CPUs are not supported in Dual mode; however, they will run in single mode on a dual board.
     
  8. How do I find out the model number of my motherboard?
    To find out the model number of your motherboard, check the top left corner of the manual, or between the PCI slots for a four digit number, for example: S1590.  In addition, all of our motherboards are all silkscreened "TYAN COMPUTER" between the PCI slots.  If you do not have this silkscreening, your motherboard is not a TYAN.
     
  9. Suggestions for System Assembly
     
    • We recommend that you have knowledge and experience when building a computer from scratch. It can be tricky!
    • Always do a fresh install of your Operating System with a new motherboard by formatting the hard drive. In some cases (for example, converting over from one file system to another), it is best to "redo" the hard drive Master Boot Record with Microsoftīs FDISK utility using the "A:\fdisk <space> /mbr" command.
    • When building a system, start with a "plain-vanilla" setup. This means using only a video card, CPU, and memory installed. This eliminates potential conflicts. You may then subsequently add more components one at a time while checking for compatibility and functionality.
    • Double-check your CPU and memory voltage settings before applying power.
       
  10. Suggestions for Server Machines
     
    • If you are running a server machine or any other critical system, HAVE A BACK UP system. TYAN COMPUTER is NOT responsible in the event a server machine or any other critical system (built with a TYAN motherboard) becomes defective.
    • Double-check CPU and memory voltage settings before applying power.
