    I decide to share my researchs and little knowledge how to MOD his own bios at your own risk.
    To find the software, a little research on google is easy.
    All Your experiences are welcome to be shared too if these methods are trully working
    EDIT: bios flash good since tried :)

    I still didnt install any customs bios like this into my p870kmg. Waiting release of 2080rtx, receiving an i9 and a flasher in case to try it.

    To BACKUP your BIOS: WORKING
    Launch AFUWINGUIx64 in admin (link ), open in admin then click save bios. Extension will be .rom. Keep it somwhere safe if like usk key and make a copy in your desktop to play with this rom file.

    1)To Instal custom boot Bios Picture: WORKING
    You need to use UEFItool 0.25.1. ( search on google: UEFItool 0.25.1 or even 0.26 )
    Open in admin and select bios file , then push ctrl+F, in the table who just open select text, disable unicode, and write BM; find and select the first 7BB28B99, double click it then on the menu who appeared: click on logo.bmp to make appeared a line with: raw file. and scrool down to find oemlogo1 also. Both of them have to be edited. You can extract them with right click and select: extract body in "all file" type to rename them into XXX.bmp
    EDIT both of them ( with paint or any software to not loose size when saving them ) and replace them with right click : "replace body" . Save the bios file and it should be good.

    2)To Mod bios to unlock hidden feature, you can use AMIBPC 5.02.00023 ( you can find it on this nbr thread :) WORKING
    Open in admin amibpc, select a bios to edit ( if it doesnt show, select all file type )
    In setup configuration each access you desire to appear in your bios Need access named "USER" to be shown in your bios Menu. Selected items have to be ''USER'' to be not hidden. Mod it then save your bios.


    3) To add microcode= new CPU i8-i9 abbilities: MMTool Aptio ( google search: MMTool Aptio 5.02.0024 ) DIDN'T Test
    Open in admin, click "load new image" to select the BIOS with New microcode you desire to add into your modded bios.
    Then go into CPU Patch case, click browse to save microcode where you want. Then select a microcode and click "extract a patch data" then Apply. Each microcode need a new browse saving
    To Inject the new microcodes, open you Bios go in the same case, select each time in Browse menu your microcode backup and instead of extracting select "insert a patch data "
    Then save your Bios.

    4) To install your Mod bios, you can use a programmer or usb update shared by members for coffe lake release update.

    let's be able to mod ourself our bios :)
