Xeon E5405 in Asus P5KPL-CM

Hello everyone,

I've recently acquired an Asus P5KPL-CM motherboard and Xeon E5405 cpu and have purchased some stickers to convert the 775 cpu to 771 but am having trouble with the bios supporting the cpu can anyone modify a bios for me with the correct microcodes to suit?

Any help is always awesome and greatly appreciated!

Cheers.
