Hi, I'm new! Firstly sorry for my, very, bad english. I've already unlocked some hidden menus in my VAIO's BIOS (AMI Aptio), but didn't flashed yet. I have some question about BIOS/EC modding. In BIOS I don't have any menu about UEFI boot (neither in Strings section). Could be possible to add it? What are the advantages in modding EC firmware? There's a tool to do this or is possible only via hex editor? Any link to a good guide? (I have some troubles with Windows 8, could be fixed with an EC mod?) Thanks!!! PS: I have a full dump of both BIOS flash and EC flash, made with an SPI R/W device.
