  • Small computer system interface ("SCSI") controller
    Patent number: 5812821
    Abstract: Disclosed is a data processing apparatus that has two or more internal SCSI devices, to include a SCSI controller, that can also accommodate eternal SCSI devices via a port connector and that can manage the ID numbers (identification numbers) of the internal SCSI devices separately from all the other SCSI devices without requiring any action by a user; and a method for controlling such a data processing apparatus. According to the present invention, ID numbers can be written into internal SCSI devices. ID numbers that do not collide with the ID numbers of the externally connected SCSI devices are assigned to the respective internal SCSI devices. The system can automatically write the ID numbers during the booting process or when the system configuration is physically changed. Even when there are SCSI hard disk drives installed both inside and outside the system, the ID numbers of the SCSI hard disk drives that are internally positioned can be read so that the internal SCSI hard disk drives can be designated.

  • System for selectively communicating information between processor and built-in keyboard and external input means
    Patent number: 5530893
    Abstract: A data processing system having a built-in keyboard and an external input device which are alternately activated. If there is no command from the external keyboard (106), the external keyboard is invalidated (108). If there is a command from the built-in keyboard, it is transmitted to the CPU (110-114). If there is a command from the external keyboard (106) and the command is RESEND a previous command is transmitted to the CPU. If the command is not RESEND, the command from the external keyboard is transmitted to the CPU.
