The make/model of the machine or the motherboard would have been useful so the forum could help you find the IDE or motherboard drivers.
More reading at http://support.microsoft.com/default.aspx?scid=kb;en-us;Q310123 It notes Code 10 which again asks to install the drivers (for the motherboard).
Even more to ponder at http://reviews.cnet.com/5208-6122-0.html?forumID=44&threadID=25406&messageID=290720&tag=
My DVD Rom and my CD-R are gone from device manager and are not shown when I open "My Computer". They both are powered and open and close just fine. They appear to be reading a CD when inserted but nothing happens. In device manager the primary and secondary IDE controllers have those yellow exclamation points. Both controllers have this status:This device is either not present, not working, or does not have all drivers installed.(Code 10)Under the performance tab, all the remaining drives(C,D,E)are using MS-DOS compatability mode file system. Both of these problems(the missing Rom's and the MS-DOS thing) occured at the same time. Nothing had been changed or removed or upgraded. I tried removing and reinstalling the Standard Dual PCI IDE controller but that did not help. I've run a virus scan as well as Adaware and found nothing. I have no clue what to do, can anyone please help? Thank in advance. Sorry about the long post but I wanted cover as much as possible.
