Bios Mods -The Best BIOS Update and Modification Source

Hi com,

I am new to this forum, i got here because I need help with my mainboard. 

I got an OEM PC from Asus (Asus CG8565) with an P8Z68-V PRO Mainboard. The problem is, the board has an OEM Bios, so very limited settings and options. The Board looks exactly the same and got all Ports and everything, so i think just another bios.

Now i wanted to ask you if i can flash my OEM Bios to Retail Bios?

I also found Bios Chips in the internet, would it be possible to just replace them? 

My current OEM Bios: http://dlcdnet.asus.com/pub/ASUS/Desktop...1471166454

Retail Bios: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1...1471166454

I hope you can help me .

Best regards.
