ABSTRACT:
A system for assigning addresses to devices interconnected on a small computer system interface (SCSI) bus. A device address bus independent of the SCSI bus interconnects address assignable devices on the SCSI bus. The devices, each of which has a SCSI ID by which it is identified and being set with default bus address information representing the SCSI ID, are connected to one or more address lines on the device address bus. A system user can selectively reconfigure the bus addresses of the devices by utilizing a personality unit to override one or more bits of the bus address information. The personality unit includes a bus address selector, coupled to the device address bus, which selects address lines according to user input. The selecting of an address line effects a change in the default bus address information associated with the one or more devices connected to the selected address line.
