.SH NAME
\fBisohybrid.pl\fR \- Postprocess ISO images for hybrid mode (Perl)

.SH SYNOPSIS
\fBisohybrid.pl\fR [\fIOPTIONS]\fR \fIIMAGE\fR

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

available as isohybrid(1).
