The support for other boot image types is sparse.

An MBR is generated together with the El Torito boot record if the boot

image bears the isohybrid signature of ISOLINUX 3.72 or later. It will
|

occupy the first 512 bytes of the emerging ISO image and enable booting

from media which appear as hard disk rather than as CDROM. An MBR does

not hamper CDROM booting. The MBR of a follow-up session can get in

effect only on overwriteable media.
