Then after vnconfiging it, mounting it up, and writing files to it, when you are happy with it, you *dd* the image onto the writer. As far as I know, that writer is not considered a writable device by the WORM driver yet. When it is, you can follow the above process to "burn" CDROMs. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
