Tyan Tempest I5000VF Harpertown support (Power Management)

[Tf2k]

Hello,

i dont know if i am in the right section, if not; please move.

it is possible to add Power Management Support to a Phoenix Bios, which recognizes the cpu but does not officially support it?

i am running the Tyan Tempest I5000VF Board with a Harpertown Intel Xeon L5420.
The Board-chipset is a Intel I5000V.
The Board recognizes the CPU String, but runs without Power-Management, which worked flawless with the older (supported) CPUs.

Tyan does not offer a new Bios with full support, but a similar board from Supermicro(X7DVA-E) supports the Harpertown CPUs.

So, could it work by copying the microcode and Power-Managment Sections from the supermicro Board?
Sadly, Tyan only supports Harpertown CPUs with another Chipset and AMI Bios.
