    When you are booting from the board when pressing BIOS against the board, you have to be very careful not to move BIOS around. If you short +3V3 or Ground pins to other pins the board can very well become unstable. I've been using a flat blade screwdriver with double sided 3M moulding tape on it to hold BIOS SOIC in place.
    BIOS is only used during the boot-up. Even then data is first copied from flash to RAM and executed from there. Once the BIOS is copied during the boot, it is no longer needed by a system.

    I have no clue on where this s**t is in new BIOS, only because I don't have a board for testing. Without trial-and-error method it will take months to figure this out.
    I must say that only BIOS region is protected, so you can reflash ME and GbE as fine as on old BIOSes, and BIOS regions can be programmed with USB BIOS Flashback, so this protection is somewhat useless.
    Anyway, I don't have so much time to dig into this, and I will return to cracking this stupid useless protection right after bying ASUS Z77 board.

    Can you tell me how to do this?

    I have an ASUS Sabertooth Z77. Cannot flash any modified BIOS at all. :(

    As I have already said: BIOS jailbreak incoming. I don't know if we can do anything about this, besides not bying closed hardware. If they will implement any sort of hardware flashing protection for BIOS chip - I will replace the chip itself. If it won't be any possible - then f*ck them, current PCs are fine too.

    Noop, its the signing key required for Asus bioses to insert capsule/module data while modding with New Module method.

    Leave it as it is.
