Hi
Your bios is rewrite protected...you need SPI-programmer+SOIC8 clip only

Ok I can get the programmer very quickly but first I will need a bios with advanced unlock functions !

Acer seems to offer two types of BIOS one specific to eufi -13mbytes- and the other not -8mbytes- which is rather unusual, which complicates things, and I ask how I make the internal changes to the bios...

it's been a very long time since some research to unlock bios (Phoenix SecureCore Tiano).

I had believed in possibilities at one time but it doesn't seem to work on my side : https://www.bios-mods.com/forum/Thread-T...ngs?page=3

Version 1.22 would be the version to be considered and modified as a priority : https://www.bios-mods.com/forum/Thread-aspire-v5-531

There seems to be absolutely no known tools to modify this BIOS, I have tried pal badly in the best of cases we can observe (UEFI Tool) but no modification is possible.

UEFITool 0.26.0 (just view)
UEFIToll NE A55 (decompression unknow/just view)

Intel Microcode.dat Converter (ok it work...)
CBROM (no enought space error...)

PhoenixBiosEditor 2.2.13
Universal IFR Extractor
andyp's PhoenixTool
MMTool
MMTool Aptio
