El Torito is an extension of ISO 9660 format that specifies a standard way to make "bootable" CD-ROMs and DVDs. It was developed by IBM, and Phoenix Technologies.
Identification
One of the ISO 9660 volume descriptors begins with the byte sequence 0x00 "CD001" 0x01 "EL TORITO SPECIFICATION".
For the usual ISO 9660 file format, the sequence will appear at offset 32768+2048×k, for some smallish value of k≥0.
