check-bios-nx – determine if BIOS has blocked CPU’s NX capabilities
check-bios-nx [-h|–help] [–verbose]
-h|–help – display a help message and exit
–verbose – explain in detail what has been detected
This program attempts to determine if the running x86-based CPU has NX
capabilities (regardless of it being disabled by the BIOS).
If the CPU is NX-capable but the nx bit is missing from flags, exit 1
(i.e. “BIOS settings need changing”), otherwise exit 0 (i.e. “nothing
wrong with BIOS”)
