16.3.17 cpuid ------------- -- Command: cpuid [-l] [-p] Check for CPU features. This command is only available on x86 systems. With the '-l' option, return true if the CPU supports long mode (64-bit). With the '-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 '-l'. This may change in the future.
