    I have modded the BIOS for my ASUS P6T Deluxe V2 board with little confusion on my part.
    Now I'd like to mod the UEFI BIOS for an ASUS P8Z77-V board.

    Phoenix tool v2.14:

    When I load a fresh d/l'd BIOS v1805 I get Info popups:
    1. Recovery file names: Z77VB.CAP; APTC022.ROM
    2. Complete SLIC (2.0) (AMI OEMSLIC ) (x1)


    Then, I load the ASUS SLIC file (ASUS.BIN) pointed to by Phoenix tool from within its folder.
    Then, I load the ASUS SLP file (ASUS.txt) again pointed to from within its folder.

    Then I load the certificate ASUS-_ASUS_-2.1.XRM-MS from the file: SLIC 2.1 BINS 1-31-2011.7z.
    Or, I load the same ASUS.xrm-ms file that I used to activate Win7 on my ASUS P6T Deluxe V2 board.
    In either case, I get the following info popup:
    Complete SLIC (2.0) (AMI OEMSLIC ) does not match certificate (x1): ASUS.BIN Matches certificate.


    I am really having trouble understanding how the mod of a UEFI BIOS is accomplished.
    But, I think that Phoenix tool is telling me that I need an ASUS SLIC 2.1 for my board.
    Or, I need a certificate and BIN file to match the SLIC file.

    Can anyone give me some guidance on this?

    Use directory " OEM" from Phoenix 2.14 and everything will work fine.

    Thanks zdenek for your response.

    It seems that I need the answer "dumbed down" for me, so that I can understand what is required.
    As I reload the items into Phoenix Tool, nowhere do I find a way to relate "Use directory "OEM" from Phoenix 2.14" to what is happening with the Phoenix Tool.
    Sorry for being so dense.

    Ok, I use a mb Asus P8Z77-V-LX and always from the 801 bios version until the 1701 I modded the bios files with Andy tool, dynamic mode, without problems. After I flashed with the Asus EZ2 bios flash program.

    All the answers from the Andy tool are correct: the Asus AMI bios has the Slic 2.0
    you load the Asus Slic file from the andy tool folder. And also this is ok

    After you verify with a Asus2.1.xrm-ms certificate and this off course match the asus.bin with slic 2.1 and not the slic 2.0.

    The last command you must give is GO and the tool produce a file P8Z77V-SLIC. CAP that is the modded bios with SLIC2.1

    After this you can flash your mb.

    Make carefully all the operations and be aware: I used Always to buy a spare bios chip (about 7-8 euro) it is socket mounted on the mother board, but until last 1701 bios never been any problem.

    I had problems with the last bios version 1801 for my motherboard, the P8Z77-V-LX: during the flash operation -> security problem and the flashing operation stopped without problems fot the mb.

    Thanks patrik,
    OK, I think that I understand what needs to be done now.
    I was afraid to do what you're telling me, but that was the only way I could see to go.
    I needed to be told that it was OK to do.
    This board has a v1606 BIOS. It seems to have no problems so far.
    I will d/l and mod that version to avoid potential problems.

    You have to allow for the fact that I am 70 yrs old.
    I can usually get things figured out.
    But, this was throwing me.

    Thanks again both zdenek and patrik for your help on this.
