    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.

    The BIOS is modded and Win7 is installed as an OEM product.

    Foe anyone interested here is how it was done:

    That is a revamp of the instructions for the old style ASUS BIOS mod.

    Thanks again guys.
    I did not find modding a UEFI BIOS to be intuitive.
    I needed the help.

    I was doing this for my gal friend's new PC that I've just built for her.
    I'm so jealous about how quickly it boots, and the other included things that I've had to add PCIe cards to get on mine, that I'll be building myself a new one soon. I'm drooling over an i7 3930k, but will wait to see what comes out as the next hex-core.
    I've needed to learn this, so that I can do mine when I get it done.
