[REQUEST] PLEASE HELP ME! HP G62 b67es

Hi! I'm trying to install OS X on my computer, but the WIFI card and also my Intel HD Graphics card is not supported. My laptop is an HP G62-b67es, Pentium Dual Core 2.00 GHz, ATI Mobility Radeon HD5470 and has 4GB of ram. I know that the ATI card is supported in OS X but i can't select it to boot as default because my BIOS is locked. The BIOS is an InsydeH20 Rev. 3.5. Please can someone help me and remove the whitelist to change my WIFI card and activate the advanced options.

Here is my BIOS file: http://ftp.hp.com/pub/softpaq/sp55001-55500/sp55430.exe

THANK YOU SOOOOOO MUCH
