I have a Dell Dimension 4500, 2.8 GHz P4, 1Gig RAM. I loaded Vista Home
Premium onto a spare partition so that I dual boot with XP. I have a
DVD ROM drive (Samsung) - which Vista detects and displays every time in
My Computer and Device Manager. But my NEC CD-RW it does not see - not
even in Device Manager. I can make it see the drive by using detect new
hardware and opening and closing the drive at about the same time. But
after a reboot it disappears. If a CD is left in the drive it will
detect it. XP sees both no problem (as does Xandros Linux which is on
another partition).



A Google search uncovered a registry hack - MS KB320553 but Upper and
LowerFilters as specified in that hack do not exist in the registry

Am I missing something? Does anyone know what causes this and how to
fix. So far the only suggestions use the upper, lower filters mentioned
above, but they are not in the registry.

Thanks

Guy

Then put them in and set the limits and reboot. If it doesn't work, remove
the entries.

What limits would I use - are there some default settings. I should
mention I have both a DVD and CD drive - the DVD drive is detected
correctly and shows up under the registry key mentioned in the
knowlegebase article.

Also - there are Upper and LowerFilter entries elsewhere in the registry
(mouse and sound card I think). I suspect deleting these would cause
problems?
