Question : PCI Device - Driver Missing?

XP is telling me that it's found new hardware and can't find the driver.  It's moniker is "PCI Device".  I don't know where to look for this driver.  I looked in Device Manager for uninstalled hardware.  No such items are present.  There is a "PCI Device" the IDE ATA/ATAPI controller devices.  It looks like it's installed properly, though.  System Information -> Components -> Problem Devices reveals no items.  How can I solve this problem?

OK - Fixed it.  I cheated.  I had another laptop, same specs, and copied over the inf directory contents into a temp folder to see if the installer liked any of those files.  Turns out it was the SATA controller.
