Abstract

Interface processing method and technique for computer system type detection with single-chip microprocessor firmware and specified keyboard, its firmware steps comprising: (1) after firmware execution, with delay of 300ms of stability for maincomputer, this system sends ll bits of BAT CODE by AT/PS2 mode, the data is AAH, with intended reverse direction to generate errors; (2) continue trying of sending errorous BAT CODE, until this code is sent. (3) detect the last data of sended code if it is LOW, then the system is XT type, and this system enters XT program execution, reset data and set CLOCK. (4) If the data is not reset by computer, detect CLOCK and data after lms delay. If both are reset by computer, then this system accept the command of computer. If data is RESEND or RESET, then this computer is AT/PS2 type. (5) If the command is not one of assigned command, or the acceptance is failed, then this system junyosout and tries to send errorous BAT CODE.
