hello i want to unlock my bios from toshiba satellite c55-a manually, i tried to unlock my bios with insyde h2oeze and change some setting in setupbrowser module my bios form is very strage in bios wrote Toshiba setup utility not insyde h2o setup utility, when i wrote full dump in laptop spi chip, not boot so i think is a signature in bios i have stock bios i tried to modify in same program here is results:
This is a signed BIOS image.
Please re-sign it once it's modified and saved,
otherwise it may cause boot failure.
so my bios is signed, my question is how to sign modified bios file and flash it back in laptop i have flash descriptor unlocked but don t work to write in chip with intel fptw: protected registers are set by bios prevent flash acces
