Requesting Update to Agesa and BIOS unlock

[deviant biologist]

Hello,
I've been trying to modify my BIOS to include the most upto date AMD Agesa update so that I can upgrade my processor from Athon to Phenom II. Currently, my BIOS do not support these types of processors despite being the same socket (S1). Thus, I need someone who is familiar with these types of BIOS (UEFI?) to modify the originals to include the AGESA update and the advanced user interface (unlock).

Please advise if you're up of the job and its cost, thanks!
