Non functional nvram

Khryzantema

Long story short my whitelabel b550m has non functional nvram and no bios update that fix it, i cant add kernel parameters to clr-boot-manager because it crashes with efi errors, what are my options? (OS is booted on uefi with csm off.)

You need to break it down more and describe what led up to your issue.

Axios my motherboard has a limited bios that nvram doents work (this also happens on some notebooks), so things like the clr-boot-manager can't create efivars, i was trying to add this kernel parameter "video=HDMI-A-1:1280x800@88" so i can overclock my monitor, but when i run clr-boot-manager update it errors out with these logs

and yes im not on legacy, there is some force flag to clr-boot-manager?

Khryzantema Run this from terminal and show output (dmesg | grep "EFI v")
Then run (efivar --list) and show that ouput
