    Hello all,

    I would like some help modifying my Zotac Pico BIOS. I have read (and re-read) JRandomHacker's tutorial on AMI Aptio UEFI Menu Unlock. I have made some headway following the information he presented.

    Using UEFITool, Universal IFR Extractor, and a hex editor I was able to enable an option that was previously greyed out.

    I tried using AMIBCP. It shows me the menu and I change the Access/Use to USER for each entry that does not show. When I try to save the modified file, AMIBCP gives me an error: Error occurred in BIOS rebuild (#80000015). I also get this error if I try save an unodified BIOS to a new filename.

    The newest version of AMIBCP I can find is version 4.55, and it gives the error when trying to save the modified BIOS.

    Back to the IFR. I have tried several other modifications, but have not yet managed to enable any additonal menus.

    I am not able to post links yet, but the bios can be found on zotac.com. Click on Support->Download, then search for PI320-W2.

    The specific menu I am trying to enable is "Security Configuration" Of course, if I manage to enable it I will try to enable all the hidden menus.

    Is there a newer version of AMIBCP than the 4.55 I am using?

    One oddity with AMIBCP is the menus that are available in setup do not show their name in AMIBCP. See attached image. Any of the main menu sections with a name on the left side are not visible in the BIOS setup.

    Any guidance on how to enable the other menus is greatly appreciated.

    This is the IFR section I changed to enable the greyed out option:
    0xE68F             Variable 0x218 equals 0x0 {12 06 18 02 00 00}0xE695             Grayout If: {19 82}
    0xE697                 Variable 0x218 equals 0x1 {12 06 18 02 01 00}
    The last line became:
    0xE697                 Variable 0x218 equals 0x0 {12 06 18 02 00 00}
    Pretty simple change but it does make the option active now in the BIOS.

    Thank you,
