Abstract:
A method for writing fixed packet data to create a re-writable compact disc that is bootable in dual modes, each fixed packet including a set of data blocks, wherein a set of link blocks separates two consecutive fixed packets, the method comprising:writing a first packet onto a re-writable compact disc including a boot record that has a pair of pointers for pointing to locations of associated boot catalogs, wherein one pointer is used to point to a location of an associated boot catalog; creating an emulated boot image of a source medium for the re-writable compact disc; for a first device that is capable of reading the link blocks, writing a first boot catalog in a second packet, wherein the first boot catalog includes a pointer to a location of a first boot image that can be executed to boot up a computer system; for a second device that is capable of skipping the link blocks, writing a second boot catalog in the second packet, wherein the second boot catalog includes a pointer to a location of a second boot image that can be executed to boot up the computer system; writing the first boot image by emulating the source medium having bad sectors that correspond to the locations of the link blocks in the compact disk such that reading of the first boot image is not interrupted when booting up the computer system from the first boot image; and writing the second boot image without emulating the bad sectors corresponding to the locations of the link blocks in the compact disk.
