ABSTRACT:
A virtual floppy disk region having the same contents as that of a floppy disk for starting is provided to a magneto-optic recording playback device (MO) as an external mass storage device of a personal computer, and makes the system start-up from the OS stored therein possible. A MO 18 which conforms to SCSI comprises a media-region management information storage region 18a, a virtual floppy disk region 18b having a storage capacity the same as that of a floppy disk, and a user's region 18c which stores data and programs and has a large storage capacity equal to or more than a hard disk. The virtual floppy disk region 18b is stored with a starting program which is the same as a starting disk and a device driver 20 for the MO's use. Also, a virtual floppy BIOS which is a program for calling the virtual floppy disk region 18b at the time of system starting is provided separately.
