Bios Mods -The Best BIOS Update and Modification Source

Hi, I have a GA-Z77X-UP7 which is not working, i think that both ethernet (2 on the board) and audio are all dead, so i want someone that could disable it by default in the bios.
Thanks for all

There is the bios i want to be custom : http://www.mediafire.com/file/2gm12r3ala...UP7.7a.zip
