Bios Mods -The Best BIOS Update and Modification Source

Hi, guys
Help me, please. How i know, there is no way to mod bios for 4515s, but somebody told me, that i can change pid/vid of new WLAN card and it will work.
Tell me, please, how can i do this. How to mod drivers?

And three years later... is there any chance for modded bios to run the intel wlan card?

Thanks.
