How can I determine if the NX bit is enabled? What I am doing right now is trying to run rdmsr, but I get an error:
rdmsr:pread: Input/output error
This is when I do:
rdmsr 0x1a0
The CPU is an AMD A6 3400M APU with Radeon HD Graphics.
I am running Fedora 18, and the reason I want to check if the NX bit is enabled is because I'm getting an Error Code 0x0000005D while trying to install windows 8 on Gnome Boxes.
That gives me the following error
rdmsr:pread: Input/output error
