This sound very cool until you need to go read/write. As soon as you need a Dos partition you might as well boot from that. When my Zip drive still worked I booted from floppy disk and then used the Zip drive for Fractint. That worked very well and the zips i/o was actually fairly worthy. My pipe dream is to have my DVD-RAM drive look like a hard drive to Dos. I don't know if its possible. In any case, in order to run Fractint from a Dos environment, I need to dedicate my machine to that or have another machine just for that (which I don't at present). But the ultimate boot disk is cool, I'm going to have to make me one of those! Roger -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
