Can i get general instructions for modifying AMI bios ?

Download the USB package, and then edit the IMAGEFH.rom, may or may not be same you mentioned (File size is 6.50MB)

Removing whitelist is done via assembly/disassembly app and hex editor, here is general info about that (not specific to this BIOS, BIOS type, or any BIOS really, just "in general")

Is the error you are looking for the exact one you are shown?  I don't find it either, using UEFITool or extracting setup and several other modules and checking those as well.  Makes me think maybe you have wrong error terms?  I even looked just  Unauthorized network and could not find that either.

Found it!  Use UEFITool, via search go to GUID CEC0D748-7232-413B-BDC6-2ED84F5338BC and extract PE32 as is, and the submodule with bunch of zero's on the end.  The one with all the zero's holds the text for the error, the PE32 module is where your block coding will need to be edited

I find three instances of Test al, al in assembly that lead to infinite loops, so not sure which applies to your hardware issue, you'd have to test bypassing each one at a time.

Hi Lost_N_BIOS and chaus - this entire thread is very informative. I am working on this same project myself on an M73 and am having a hard time progressing. How did you find this GUID? I am unable to find any of the error text as you did. My ROM dump (obtained from board with CH341A + SOIC8 SOP8 Clip) is attached

Attached is my edited bios, I hope that helps

Thank you!! I will be trying this on my machine as soon as I get home tonight. Will update here!
