ABSTRACT:
A computer system capable of booting currently manufacturable CD-ROMs or tapes without altering the ISO standard or requiring special, customized software to perform this function. A CD-ROM developed for booting according to the present invention contains a boot record as defined by the ISO but located at the end of the defined system area. The operating code of the computer scans for a boot record starting at the beginning sector of the CD-ROM and ending at either a default number or the volume descriptor terminator. The floppy disk boot images are contained at the end of the primary volume space and incorporated in the primary volume space, not external to the primary volume space as in the ISO standard. Boot code contained in the boot record determines the size of the volume, and the proper floppy image to be used and then the actual location of the floppy image. Booting of the system then commences using the floppy image.
