//**Note:** I/O instructions are not available when the processor is in user mode, but can be executed only by the operating system kernel in system (privileged) mode. They are thus of limited interest to regular application programmers under most operating systems.// | //**Note:** I/O instructions are not available when the processor is in user mode, but can be executed only by the operating system kernel in system (privileged) mode.
