  Tyan S1854 Tazer II series are in fact stock Tyan Trinity 400 series boards 
  and the Tyan BIOS files may be used on them without problem,
  providing many more user-settable features that can improve performance and 
  CPU support beyond what the
  Micron or Tyan specifications say. (These have both Socket 370 and Slot 1, use 
  only one at a time.)
I had one labled 99MOAB REV C. Extensive searching revealed this revision would 
  support PIII "Flip Chip"
  CPUs with the latest Tyan BIOS for the Rev. 3.0, even though Tyan's specifications 
  say it won't.
It correctly recognized a PIII 933Mhz and ran Windows XP with no problems. 
  (Still running fine with its
  new owner.) I've no idea what the fastest CPU is it could support. I suppose 
  it mainly depends on what
  ability the BIOS has to detect the CPU voltages and reprogram the voltage controller 
  to match. (Which was
  supposed to be why this particular board could not support flip chips.)
