[Guide] How to Use a CH341A SPI Programmer/Flasher (with Pictures!)

[dulehak]

I found this post for my answer.

Need advice on replacing system info in BIOS that is to be flashed.

@Binkodyl - In Gigabyte BIOS, only MAC ID is stored in GbE region of BIOS, you can replace that easily via UEFITool 25.0 + hex editor. Or you can use hex editor directly on entire BIOS, GbE region starts at 1000h, first 6 bytes there are the MAC ID Placeholder (88 88 88 88 87 88) that you replace with your real MAC ID For MX25L12873F use CH341A v1.31(1.4) (CH341AFree) (This is the name of the folder), ASProgrammer 1.4 or 1.41, or CH341A v1.1.1.32 http://s000.tinyupload.com/index.php?fil…213094…

Thanks for your help, you put me on right way.
