In case it's not widely known, let me quote isolinux.doc: 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. It would probably be a worthwhile additional feature for the Debian Installer. -- Cheers, Feri. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe".
