About a month ago, after installing a modded bios, i wanted to go back and forth between my original and the modded one made here (Which worked perfectly BTW). Though upon reverting i always encountered 'Can't Analyze the IIM Information' , the internet provides no fixes for this, and acer wanted to replace my mobo, which was too much of a hassle for me even though it was free. Today i present a way in which you can all flash your bios which gets this error, and many other errors. There is 1 warning though, this will flash all bios files, regardless of mismatches and such, so you must be 100% sure you are flashing a compatible bios because you will not be told if it isnt, it will just flash.
This is what you do. Download the Engineers version of AFUDOS attached here. Format a DOS-USB. Then place the AFUDOS.EXE file into your formated USB along with your ROM file.
Restart and enter the DOS environment then enter these commands.
AFUDOS /iXXXX.ROM /pbnc /n
where xxxx= Rom Name, remember must include the 'i'
You have now successfully flashed a bios, that either has issues matching information, issues analyzing current versions, you want to downgrade and many other issues.
Cheers
