HI, I'm trying to mod the bios for my new P8Z77-V motherboard. I've tried using PhoenixTool 2.09 without success. From reading posts here it seems you can't mod the bios downloaded from Asus, you have to flash the bios and then backup the flashed bios and mod that, I'm I right assuming this? I've tried using Universal BIOS Toolkit 2 but the backup is saved with a ROM extension not CAP as the original. I'd appreciate advise. Thanks.
