Note:
First do the Noide change then remove the controllers in control
panel -->system applet --> device manager.
Reboot and see what happens. The Ciontrollers will be reinstalled upon boot
up.

Thanks for your response. There was no NOIDE key in the
registry to delete. I have removed the devices from the
device manager applet, they keep reappearing in the same
state as described in my previous post. Other than
upgrading to XP, I am not sure what the resolution could
be. ME is one of Microsoft's worse products in my
experience.

Did you ever install someones (any third party ) busmaster controllers ?? If
intel they may require special software for removal.
Try going to safe mode and delete the ide controllers -all of them.

No third party controllers were installed that I know of.
When I go into safe mode I can remove the parent IDE
contoller, but the child primary and secondary remain. I
tried rebooting in safe mode and the children are still
there.
