Re: EFI stub: Warning: unable to unprotect memory range

Hi guys

So, given that Asrock have released a fixed version, is it known whether the fix was due to the new AGESA 1.3.0.0a or is it something Asrock themselves fixed? I recently bought an X870E Aorus Master and an X870E AORUS Elite X3D, so this couldn't be more annoying.

Thanks

The only solution for gigabyte owners like us is to pester them enough them and pray they do something I tried as mentioned before and got the usual answer.

Which BIOS version are you using?

I have the b850 and I'm at the F7 version but you have to use the one before the asega 1.2.8 bios unless you have a new Ryzen CPU but as far I know this problem didn't my system but I'm no expert I downgraded anyway because who knows but yeah

Re: EFI stub: Warning: unable to unprotect memory range

Just to chime in, I have this problem on Gigabyte X870E AORUS ELITE WIFI7 (Rev. 1.2)
When I have went from FA6 bios to FA9
I have downgraded to FA7 and the error went away.
FA8 is the bios verson with asega 1.2.8.0
