Where is the signature check? Is in the bios itself or only on the flashing software? Is there a chance to flash the modded bios using another software, or using an EEPROM flasher?
Thanks for your answer Serg008. Then, You tell me that the one way to modify my Insyde BIOS is extract or desolder my IC BIOS in my mobo to reprogram it with the SPI Programmer? I can buy that device but I don't know how to use it correctly. In your last linsk is the complete steps to do it? Thanks.
