- I would guess that most people are having good luck with their scsi,
- and it is only a small minority that are having troubles. Even then, it
- appears that most of the scsi troubles fall into two categories. Most of the
- scsi problems with the new code have now been fixed, although there are
- intermittent reports of kernel crashes with people using the ST0x.
- Motherboards that are unable to do bus mastering in a reliable way continue to
- be a problem for some people, and this is something that we can do little
- about. Admittedly it does cost a little more up front, but no one has been
- able to get any solid technical information on a non-scsi cdrom drive since the
- interfaces are proprieatary. I suspect that some of them are IDE drives of
- some kind or another, but they all apparently require their own special
- controller and apparently there is no standard way of adding a second IDE
- controller.

- No the ext fs is not feasible for the cdrom, because the iso format
- works just fine, and it is an international standard format for cdroms. The
- Rock Ridge extensions make the cdrom look just like a unix filesystem, so
- I can think of no good reason to try and use the extfs on a cdrom.
