Tyan S5207 - Speedstep Update request

[Krobaruk]

Hi All,

The bios is here:
ftp://ftp.tyan.com/BIOS/S5207_v102.zip

It will open in Ami BCP V3 and looks complete. I have only ever done basic changes like microcode with AMI and dont really know where to start with Speedstep problems. The cpu I'm having problems with is a Intel T7200 Stepping 6. The speedstep bios options are present in the bios but when enabled depending on the option Linux with will load the P4 frequency driver (Equvilent bios disabled) or loads the correct acpi frequency driver but detects bogus available CPU frequencies (250Mhz and up in 250mhz increments).

Any help or hints with this problem would be much appreciated.
