I want to become a BIOS modder

[waayo169]

Hi, sorry for replying late
im trying to mod my bios (Acer 4755G), im trying to unlock older bios versions and over/undervolt my gpu and if possible disable nvidia optimus (very ambitious  ) 
ok so in the picture i use Phoenix dell/efi slic mod. in the right side are the bios that are extracted. thats where im stuck since i dont know what software to use to modify this .ROM files or get the STRINGS/TEMPLAT files. as for the 2nd picture Phoenix Bios editor pro isnt working bcs No bcp's found. and for how i overvolted my dGpu, somewhere on those DUMP files is my vbios. i tested every .rom files with 64kb with NiBiTor. its just that when i use the vbios from Techpowerup it doesnt work and still useing the stock vbios version.

Thank u for replying ^_^

Hi!
It seems Steven misunderstood you. You have EFI / Insyde BIOS, so the files mentioned by him cannot be found in the DUMP folder. I can only give you the software that I used to create this mod.
UPD: I guess you did okay.
