Answers :

I also have the same problem. I've tried all the above plus some added info. The floppy still works when I swap it with the DVD. Occasionally it works for a short time right after a hard boot but soon after it appears to uninstall. I have searched the net for answers to this problem without success. I tried the registry correction without avail. There has been some online comments that the problem appeared after an auto update from uSoft. I believe the problem is software or firmware related.
I took it to a local PC repair and found out it is on the motherboard. I tool it to a swap meet and plugged in a replacement CD player (R40 device), and the screen popped up "error on device". So, it's the mother board... or the controller on the mother board for the device. I'm giving up and getting an external drive. Good Luck with your problem.
