Fastest PIII for a tyan S1854 Trinity 400

I have a Tyan S1854 Trinity 400 M/B with a 600MHz PIII in it running on a 133bus. I'd like to know what's the fastest PIII chip I can put in it.

On my Boot up screen, I get the following:
<font color=green>
Tyan S1854 Trinity 400 Rev.0.81

10/20/1999-694X-596B-977-Rev.0.81C-00
</font color=green>

It has an Award Bios and Via chipset.

  3. There are two identifiers on the board itself that will tell what processor can be supported. It is also limited (at 133 fsb) to 1ghz p3 fcpga only. Look for 99PON by the ram slots and "J" or above, kinda up from the battery, towards the ram slots. Also look on there web site under support, it's all there. There web site is pathetically slow and I have cable.
  4. Mine is a Rev. 99M0AB

    Tyan techs say it's not compatible with anything above 866/133MHz. But i want to know exactly why it's not compatible. There a newer BIOS out for the board (Award ver. 1.07) that supports 1GHz. Would a BIOS update make it possible? Or is it a required power problem? If so, aren't there fixes for that? Is it just the chipset, etc. I just want to know exactly what it is that makes the board not support over 866 and if there are any ways around that limitation. when I bought the board the 1GHz PIII was just around the horizon and I bought it with plans of upgrading it to that in the future (bought in late 99).
