Does cdwrite work under FREEBSD ? > Thanks. Linux' cdwrite itself won't be ported. It does all the SCSI handling itself, which is not what i believe being Good Coding Style. FreeBSD does already have a `worm' SCSI driver that's supposed to handle this class of devices. FreeBSD 2.1R's worm driver should at least be able to recognize your drive (simply add a ``device worm0'' to your config file). Note that although the driver does no longer panic your system on a regular basis, it's still somewhat fragile and rather `experimental'. (Trying a dd(1) on /dev/rworm0 should yield you a ``Incorrect command sequence'' SCSI error.) cdwrite splits into two parts: * prepare the drive for a write operation . For FreeBSD, this could be handled by some invocations of scsi(8). Eventually, it will move into the worm driver some day, and be controlled by something like wormcontrol(8). * actually write the data . For FreeBSD, this could be handled by dd(1). I'm currently in the process of experimenting with the above options, so perhaps i might end up with a Perl script that hopefully will give me a burnt CD some day. Once i've got this working, we will discuss how to go on. Don't expect something useful before 1996. :-) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
