@subsection cpuid
@deffn Command cpuid [-l]
@deffn Command cpuid [-l] [-p]
Check for CPU features. This command is only available on x86 systems.
With the @option{-l} option, return true if the CPU supports long mode
(64-bit).
With the @option{-p} option, return true if the CPU supports Physical
Address Extension (PAE).
If invoked without options, this command currently behaves as if it had been
invoked with @option{-l}. This may change in the future.
