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.
