DESCRIPTIONThis 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")
