After reading this newsgroup, I haven't found a solution. Therefore here
goes.
My desktop machine recognizes two CD/DVD drives in BIOS, but that's all.
They don't show up in the device manager or Windows Explorer. It's as if
nothing at all is there. I figure I need to reinstall some drivers but
don't know
where to grab them. I'm using VISTA ULTIMATE with the latest SP.
Short of removing them and installing new ones, I would rather try some
fixes.
I hooked up my HP external CD/DVD and it also isn't recognized. I can't
install the installation CD since I don't have a drive. HELP.
Any and all suggestions would be greatly appreciated. Fortunately for me
I have a top of the line notebook that's actually a desktop replacement.

This is for XP but it worked with my Viata Ultimate 64bit.
First Backup registry - not really necessary but just in case, etc.
