El Torito Structure
| El Torito booting begins by the Boot Record of the ISO 9660 filesystem at block address 0x11. See also article ISO 9660. This Boot Record points to a Boot Catalog which is stored in one or more blocks inside the ISO 9660 filesystem. The Boot Catalog lists the available boot images which may be prepared for multiple system architectures, called "platforms". These images are marked either as emulated floppies, or as emulated hard disks, or as no-emulation images. In any case they are the first stage in the boot process where custom code from the ISO filesystem can be executed. |
