NAME

       isohybrid - Postprocess ISO images for hybrid mode

SYNOPSIS

       isohybrid [OPTIONS] IMAGE

DESCRIPTION

       Starting  in  version  3.72,  ISOLINUX  supports  a "hybrid mode" which can be booted from
       either CD-ROM or from a device which BIOS considers a hard disk or ZIP disk,  e.g.  a  USB
       key or similar.

       To enable this mode, the .iso image needs to be postprecessed with this utility.
