Hello, I am trying to mod my HP m7-n109dx Insyde BIOS. Through reading through a bunch of forums, and tinkering around, I have been able to extract my current BIOS from the EFI partition, open it up with EZH2O, edit the default setup menus, and save the BIOS file. When I try to flash, I receive a signature error (obviously there's a signature file check, which seems to be a .sig file). How would I go about flashing the modded BIOS? Am I going about this wrong? My motherboard seems to have incorrect SATA settings which prevents my M.2 SSD slot from functioning. I'd love to have my BIOS settings unlocked, but am settling to just manually change the default settings in the BIOS and flash. Any feedback and/or information would be greatly appreciated! -Manufacturer: HP -Motherboard Model: 80E6 (laptop model: m7-n109dx) -Bios revision: F.25A -Bios Type: Insyde BIOS -Bios Download Link: ftp.hp.com/pub/softpaq/sp74001-74500/sp74326.exe -Bios SLIC: HP 2.1 If anyone is willing to help, I can give whatever information or files they need (rw report, unencrypted BIOS file.etc.). Just let me know! Thanks!!
