After reading extensively on whether the Tyan Thunder 100 MB (1836 - Dual Slot 1, SCSI, LAN) could support processors higher than the last "official" BIOS listed (Katmai 600) I decided to purchase 2 Slot 1 PIII 750E processors and give the Beta 2.0 BIOS a try.

I figured I had to do _something_ to set things to recognize the higher processors but after much reading I decided that the MB was just supposed to recognize them. So out come the old PII 350's and in go the new PIII 750E's.

Upon reboot, the system came up and properly identified "x2 750MHz". I let it try to POST and then boot to Win2k but it stopped while trying to initialize the SCSI devices. I turned the machine off, then back on (yep, the scientific approach) and it showed just "750MHz" like it couldn't see one of the processors. I hit reset and it then came up and identified "x2 750MHz" again, weird.

Anyway, it then finished POST and _tried_ to boot to Win2k. That's where I'm stuck. It just won't boot to Win2k.

Does anyone have any ideas how I can get some more lovin' outta my old faithful server? Oh, my board is "Revision F" if that helps any.

PS. I am aware that the voltage regulator supposedly only goes down to 1.8 and these are 1.7 processors but I do have good cooling on them.
