Windows XP does not recognize the CD in the drive when the CD is changed after bootup. If the CD is in the drive at bootup, XP will recognize and run the CD properly.


Any ideas?

This only happens on Windows XP. In these cases, I am using Pentium 4 DFI motherboards (i850 chipset) and Acer CD-Rom Drives (some with AOpen CD-RW Drives).
