Xeon E5440 Micro Update [Asus P5k SE] and [Asus P5K E/WIFI-AP]

Hello,

i got this 2 board:

[Asus P5k SE]
[Asus P5K E/WIFI-AP]

and would like to use the Xeon E5440 CPU but its seams like that i need a bios Mod to run them.
The Bios tells me "Unknown CPU... need micro update.." and the CPU Temp is show as 100°C+.

ATM i use bios mods for these 2 mainboard from this forum:

[Asus P5k SE] so that is has AHCI Support, that is important to me for SSD...

[Asus P5K-E/WIFI-AP] update ROM's

Could someone help me out with a bios mod, because i have no clue how todo them.
