Hi, is there anywhere else that I can get the code? Would like to unlock the advanced menu on my BIOS but there doesn't seem to be any deliberate skipping of the IFR forms in a subroutine that referred to all of the forms.

Hi,
Thanks for the links. I've referred to Phoenix wiki and made sense of some of the subroutines inside the module.

I found that the subroutine paired with the Advanced form has some lines missing and some different lines than the other functions paired with the other forms, so I changed some of the efi out of resources error check instructions into nop to make space for the missing lines and patched the file. 

Now I don't know how to pack the modified .MOD file back into isflash.bin. With andy's SLIC tool 2.56, selecting "no SLIC" in advanced and clicking Go results in the original file being generated, while in UEFITool NE alpha 44 right clicking PE32 image section for SetupUtility brings up a menu with greyed out "Replace body", and with the latest non-NE version 0.22.1 it says invalid UEFI volume... Do you have any suggestions for packing the bios image?

Never mind, found "allow user to modify other modules" option in andy's tool.

Thank you.

i did it with phoenix tool...

is your BIOS without lock or you have SPI programmer?

Haven't tried flashing it yet, don't have a backup computer right now. Will probably try it in about a week.

However, when trying to dump the BIOS with FPT from UEFI Shell and DOS I got no flash device listed and invalid descriptor error, does that mean my BIOS is most likely protected? I'll try to see if the crisis recovery flash works.

Also, which chip on Acer Aspire R7-572G motherboard is the SPI flash for BIOS? Can I read off it and flash it without desoldering? Can an Arduino be used to read and write to the chip?

Found it between the ram and GPU heatsink, Winbond 25Q64FVSIQ

you can try to make a bios dump under windows. you need to extract fpt win version, run cmd under admin rights and execute in a folder, where you have extracted fpt: FPTW64.exe -d bios.bin -bios . probably you'll get your bios dump. but i think you will not have possibility to write it back.

Well, I couldn't get a dump either under Windows, UEFI Shell or DOS. Crashes under windows, and reports no Flash Device Listed, and invalid descriptor region in UEFIShell and DOS...

there is another possibility to make dump of your bios. you can download a bios update from acer and change in platform.ini [BackupROM] to 1. it should make a dump file of your bios. there is more info in internet about this way, i didn't try it.
