is there anyway to repair a corrupted bios using a hex editor?

[Delphianrex]

hi dear friends,
some laptop manufactures are putting the bios update on their website instead of the complete bios file, like Sony VAIO, I was wondering if there is anyway to dump a laptops bios using a programmer and combine the Update file and the dumped file together using a hex editor? in other words, is there any technique to repair a laptops bios in the case that a laptop bios is corrupted and the screen is just black when it turns on and the update file is the only stuff I have which is half size of the full bios

Thanks in advance

i don't have all Sony Vaio Firmware or Bioses !
Let me know which model You have and your last Bios used
then I will try to find something for You !
I wrote rebuild broken Firmware not Archives Firmware
