ISOHYBRID.PL(1)

NAME
isohybrid.pl - Postprocess ISO images for hybrid mode (Perl)

SYNOPSIS
isohybrid.pl [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.

Note: isohybrid.pl is a Perl script, a C implementation of the same utility is available as isohybrid(1).
