It is a pre-mastered file system that just needs to be recorded onto a media. The size 657922048 indicates that it would fit onto a regular CD-R. > cdrdao seems like more toward audio, so i'm guessing that it's > either cdrecord or burncd.

Yes, both will work, and yes, cdrdao is better for audio or mixed forms (allthough it can burn data ISO, too, but I don't know how, out of the box). :-) You may follow my examples from Date: Sun, 25 Jan 2009 02:53:46 +0100. I'm a lazy guy, so I've setup the following aliases in /etc/csh.cshrc: alias burndata 'cdrecord dev=1,0,0 speed=16 -v -eject -tao -data' alias burnaudio 'cdrecord dev=1,0,0 speed=16 -v -eject -dao -audio' alias burntoc 'cdrdao write --driver generic-mmc-raw --device 1,0,0 --speed 16 --eject' And I've got a shell script "burndvd" in ~/bin (included in $PATH): #!/bin/sh if [ "$1" = "" ]; then echo "$0 <iso>" exit 1 fi if [ ! -f "$1" ]; then echo "$0: cannot open $1" exit 1 fi growisofs -dvd-compat -Z /dev/dvd=$1 cdcontrol eject I know this is *very* lazy stuff, but it works, and I never change a running system. :-) -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
