7 CD/DVD Boot
7.1 Overview
CD and DVD media shall be bootable if the media follows the formatting described here. This format is based on
ISO-9660, but does not require the media to be ISO-9660 compliant. Boot media shall have an ISO-9660 Boot
Volume Descriptor (BVD) at sector 17 relative to the start of the last session on the CD or DVD media. See
clause 7.2.1 for a description of the BVD. Other ISO-9660 constructs, such as the "Primary Volume Descriptor"
and the "Set Terminator" are not required for compliance to EDD, but are required if the CD or DVD contains
material that can be accessed by ISO-9660 compliant drivers. Figure 4 shows a standard ISO-9660 image
overview.
