They did something, but it's not particularly special. All they did was run isohybrid (from syslinux) on the ISO image. It uses unused space at the start of the DVD ISO specification that is normally left blank to hold a partition table so the image can be copied to a USB drive and appear as a partitioned disk. I use it all the time with the Linux Format cover DVDs, not only to make sure that they are USB bootable but also to ensure that any ISOs on the DVD are also USB bootable. --=20 Neil Bothwick There is absolutely no substitute for a genuine lack of preparation. --Sig_/QE5sZ78+Eprv.DcnkPbjPhN Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlQtwoAACgkQum4al0N1GQPPtgCfUzjCS9RAkFsvtqud3ELsC7q+ 4CwAnRVItTNRDILXUSFWSgfa37Fx7W8o =szh7 -----END PGP SIGNATURE----- --Sig_/QE5sZ78+Eprv.DcnkPbjPhN--
