The x86 for 32 bit vista..the x64 for 64 bit vista..the certs match the slics..t-2P and t-03 respective.. Probably flash x86/32 bit rom for you if no 64 bit proc. and use certs you probably have..
Thanks for your help but still no luck for my x48 board having SLIC After flashing with your modded bios, the board cannot boot again @@ i need to flash back with the original stock firmware
