  • Method and apparatus for assigning drive numbers to hard disk drives coupled to a computer system
    Patent number: 5581786
    Abstract: In a computer system to which externally- and internally-set hard disk drives can be coupled, a drive number is set to the externally-set hard disk drive and/or internally-set hard disk drive in accordance with a coupling state of the externally- and internally-set hard disk drives and a swithing state of a dip switch of the externally-set hard disk drive. When the externally-set hard disk drive and/or internally-set hard disk drive are/is coupled to the computer system, pop-up menu data for the externally-set hard disk drive and/or internally-set hard disk drive is added to the normal pop-up menu data. A pop-up menu is therefore displayed using the normal pop-up menu data including the pop-up menu data for the externally-set hard disk drive and/or internally-set hard disk drive.
