Unlocking BIOS Region with AMD MTRR

Open ages2001 opened this issue 7 months ago • 3 comments

I tested with MSI MAG X870 Tomahawk motherboard but it stucks at AMD MTRR message. Waited 1-2 hours but nothing happened. Used 1.2.0 version. Other versions say chipset unsupported.

AMD support is pretty experimental.

I need to figure out how to do that properly later.

Hi, @FlyGoat ! Will you solve this issue in near future? Because some AMD machines cannot boot Legacy Boot and some has issues.

@ages2001 have you tried with 1.2.3? Because with 1.2.1 and earlier releases, the implementation of rdmsr() was broken.
