@Background Pony #4B9D It is can be dangerous for your PC! Do it only at your own risk! Also I recommend you buy USB Bios programmer
Download clear BIOS from your motherboard site
Unpack it with use PhoenixTool
Open “<BIOS Location>/DUMP/BIOS/”
Open “BIOS\BIOS???.BIOS” with use 7-zip. It file so large, but not named “BIOS0.BIOS”
Sort files for size and try find your motherboard picture (named like “7BB28B99”, but maybe in your motherboard he can called another one)
Look a file extension and file size. You need create a new file with this format (if you have BMP, you need use BMP file) and with file size less or equal original file (If original file have 1MB, you can use file 0.9MB, but can’t 1.1MB)
Open any photo-editor (like a Photoshop or GIMP) and edit my (or other) art. For example you can transform image from 1920x1080 to 1024x768 (depends on motherboard) and crop image (black corners) to save file size
Save file with file format what you need
In “PhoenixBIOS” click “Struture”, find you file (for me “7BB28B99 - ??? - ???”), click to “Raw section” and replace it with “Replace” button
Close “EFI Structure” window and click “Yes” (Save)
Copy BIOS file to flash-drive and use firmware in your motherboard for update BIOS
