I just downloaded the files in case I needed them (before your answer) and made the confusion between the 14 and the 4, a dumb careless mistake haha… Don’t worry, I am currently using the correct file so no problem about that. Also, I’m sorry about the guide I linked, I don’t want to update the TXE ME FW, I just tried (and failed haha) to find some explanation about this error.
I tried to use MMTool Aptio 5.02.0024 and UEFITool 0.26.
I tested every modded BIOS you sent, and I have some exciting news and some less exciting…
The exciting news is that the boot logo effectively changed ! The less exciting one is that the messages is always here. It doesn’t prevents me to boot completely but I need on every reboot to select “save/discard and exit” to boot on the OS.
About the TCO Lock, would I need to use setup_var with the custom Grub ? Because this one only showed an underscore when I tried it without any way to enter any command. However I know that amisetupwriter works on this machine (Sorry if i’m wrong about that, I hope those infos are not useless).
Thank you so much for your help !
Edit: All those tests were made with secure boot disabled, without any BIOS password and with all TPM settings disabled in the BIOS before.
