    Abstract: PURPOSE: To alternatively or simultaneously validate a built-in keyboard and an external input device as necessary by incorporating a means which validates and invalidates an external input means and a data transmitting means in a controller. CONSTITUTION: A controller 28 validates an external input means 20 when no data nor command supplied to a built-in keyboard 12 from a processor 22 exists. When data or command from the means 20 exists while the means 20 is validated, the controller 28 receives the data or command from the means 20 and transmits the data or command to the processor 22. When neither data nor command from the means 20 exists while the means 20 is validated, the controller 28 invalidates the means 20 and, at the same time, transmits data or command from the keyboard 12 to the processor 22 when the data or command is inputted from the keyboard 12.

    Abstract: PURPOSE: To manage the ID numbers (identification information) of the connected built-in SCSI devices of an information processor which has two or more build-in SCSI devices and can connect the SCSI devices even to the outside through connection ports without user intervention. CONSTITUTION: ID numbers can be read from and written in built-in SCSI devices. Such numbers which do not come into collision with the ID numbers of SCSI device connected to the outside are selected as the ID numbers of the built-in SCSI devices. The writing of such ID numbers is automatically performed on a system 10 side at the time of performing boot processing or when the system configuration changes. Even when SCSI hard disk devices are installed to both the inside and outside, the inside hard disk device can be designated by reading the ID number of the hard disk device.
