    I have read just about every resource available on the topic, but would really like some input on the exact settings needed to modify the following bios:

    Please keep in mind, this isn't a mod request as there have been some already done in the requests page, I am more interested in what is actually being done with the phoenix tool to get the outcome, as everytime I do it myself, the checksums never ever match the bios files uploaded on the forums. They seem like simple straight forward module auto run mods, but something else must be getting done to the files.

    Manufacturer: Asrock
    Motherboard Model: z77 Extreme4
    Bios revision: 2.00
    Bios Type: EMI BIOS
    Bios Download Link: f t p://174.142.97.10/bios/1155/Z77%20Extreme4(2.00)ROM.zip
    RW Everything Report Download Link: h t t p://w w w.sendspace.com/file/7agtee
    ^remove spaces for links, it wouldn't let me post them =/

    When I download the modded version from the forums here (v2.00) I get the md5 > 1ceb83d303b421cf3da2a957af3cc2fe
    On my mod I get the following checksum > 637ca31a8ed5249c64768f2d242c83bd

    I've noticed some smaller changes for example in module 16D0A23E-C09C-407D-A14A-AD058FDD0CA1, at the beginning of the module, a character is different in mine vs. theirs however my version is the same as oem in that aspect.

    Code:
     3E A2 D0 16 9C C0 7D 40 A1 4A AD 05 8F DD 0C A1 C5 62 07 40 CD 92 00 F8 16 00 00 13 02 6C 14 73 02 C4 96 A1 45 A7 AF 78 E0 52 4A 0A E2 08 00 00 9D 92 00 01 94 92 00 00 00 84 92 00 10 4D 5A 00 
    vs.

    Code:
     3E A2 D0 16 9C C0 7D 40 A1 4A AD 05 8F DD 0C A1 C5 50 07 40 CD 92 00 F8 16 00 00 13 02 6C 14 73 02 C4 96 A1 45 A7 AF 78 E0 52 4A 0A E2 08 00 00 9D 92 00 01 94 92 00 00 00 84 92 00 10 4D 5A 00 
    Please can one of the mods post some screenshots, or a description of the exact settings used in Phoenix Tool 2.09 to do this properly. I'd much rather just understand it and be able to do it myself then have to hassle you guys each time there is an update (and there has been like 8 in the last few months =/ )

    Thanks so much!

    Hello, well, i'm not an expert however i make my own mods, even more, i do more than just put a slic, i put modded modules in the bios succesfully (Splashscreen images) h+t+t+p://forums.mydigitallife.net/threads/34651-Mod-splashscreen-logo-on-Asrock-z77-Extreme-4-EFI-Bios-%28MAYBE-OTHERS%29 , i have the same mobo than you and every time that i applied the bios mod to my mobo it works perfect, so i think that i can tell you how to mod your bios safely, follow thw next steps:

    1-Download the official asrock bios update (instant flash version)
    2-Open Phoenix/Dell/EFI Slic Mod and load the bios file
    3-In "Manufacturer" just select the brand that matches your bios, in this case ASRock.
    4-Select the slic file that you want to apply.
    5-Select the respective SLP file.
    6-This step is not really necessary (in this specific case): select the rw file.
    7-Leave the default options (method and advanced options)
    8-Press "Go" and wait that the program create de modified bios.

    That's all, the bios must work perfectly.

    Good look.

    Thank you for the reply, I think I was just over-thinking things too much lol. I got it working using the same method as you as well. I think the differences I was seeing were simply from different modders using different versions of the Pheonix Tool, I confirmed that depending on the version the md5 checksums would be different.

    In the end nothing to worry about and all works fine :biggrin:

    Thanks again for taking the time to answer my question :tankyou:

    Hello, your welcome ^^, you are right, the differences in checksums are mainly influenced by the version of tool, however, if you use different settings even in the same tool you surely will get different results.

    Wow, excellent! That worked.

    Just one thing.. I did formatted a USB stick (4GB) with DOS32 and did the BIOS upgrade from the Bios itself (Press F2 during boot and select "AsRock Instant Flash")

    At first attempt, I just got a blank screen and panicked a little .. I waited 15 minutes before I pressed the reset button on my motherboard. Fortunately no harm was done.

    The trick is that the USB stick needs to be in one of the two USB2 ports on the motherboard and not any of the USB3 ports (or USB header connectors).

    When I just connected a keyboard and the USB key to the USB2 ports, and disconnected all other USB devices, the BIOS update went just fine.

    Thanks again!
