I need a BIOS mod for Lenovo M55 PLEASE

Hi there, I have a request for a modded BIOS for my Lenovo machine. It is an older type and I wanted to know if anyone here would be able to modify it to update the Intel microcode as at present it is only able to use a 2.4ghz older style CPU and I would like to add a much bigger one. The machine has the ability to run a 1066mhz bus and there are much better CPU's than the E6 series. any help would be appreciated.

Manufacturer : IBM
