    You should update at least to F16h since SMMruntime is a serious security issue. As for the MATS tables in f16j, you can dump them and compare to see what got modified.

    Of course, this is assuming you didn't previously add a slic module or modded your firmware with UBU...

    Good luck.

    p.s. You can live dump the ~50kb long ACPI MATS table with either RWEverything – Read & Write Everything or 404 Not Found . A before and after should tell you what they've changed easily enough.

    Question Re: GIGABYTE Modified Bios

    Is it possible to unhide options in Gigabyte's UEFI ver F22d for Z170-HD3P? I can see them with AMIBCP 5.01.0014, but when I want to write changes to file, AMIBCP just crashes. The options which I'm interested in are named "PCI Subsystem Setting" and "PCI Latency Timer".

    EDIT: Nevermind

    Hi,

    can anyone do a mod-update for the P67A-D3-B3 revision 1.0 ?

    I think about actually Option ROM for SATA and CPU Microcode.

    best regards from germany

    Default Re: GIGABYTE Modified Bios for Z77-HD3 rev 1.0

    Here is my modded bios for Gigabyte Z77-HD3 rev 1.0:
    z77hd3-f3
    It's based on a unofficial F3 bios found on softpedia. Added NVME support from a newer Z79 bios. It's works like a charm with my Patriot Hellfire 240Gb M.2 SSD inserted on the fastest PCIe slot (moved video card to a slower one).
    If Windows won't install you must safe erase SSD with software provided by manufacturer (in my case patriot toolbox).
    Have fun!

    Can someone please modify bios for EX58-UD5 v1.0 to bypass Main bios checksum check please?
    Here's the problem. Seems like controller which uses main chip it is damaged. Tried to reflash both soldered and unsoldered, tried to replace.
    I can boot with backup bios, enter bios and reflash using Q-flash. But then i get:
    MAIN BIOS CHECKSUM ERROR
    A line about tring get bios from HPA - Unavailable
    A line about tring get bios from Backup Bios - OK
    Writing image....[flashing cursor]
    and here it hangs on latest bioses or immediately reboots on olders one.
    Backup bios operates properly. I want to bypass that main bios checksum check to be able to continue to boot OS.
    Please assist.

    Problem was caused by using chinese PCI-E x1 to 4 x1 multiplier, which also damaged two 970A-DS3P boards, but those were fixed just by reflashing bios chips.
