       This is all keyed off the PCI ID which the hardware provides.  =
Unless you are trying to ID ISA devices something like a modem it is the =

the Details tab.  The categories of interest here are Hardware Ids and =
Compatible Ids.  For example, my video adapter provides the following =
hardware IDs

      PCI\VEN_10DE&DEV_0322&SUBSYS_043110B0&REV_A1
      PCI\VEN_10DE&DEV_0322&SUBSYS_043110B0
      PCI\VEN_10DE&DEV_0322&CC_030000
      PCI\VEN_10DE&DEV_0322&CC_0300

    and the following compatible IDs

      PCI\VEN_10DE&DEV_0322&REV_A1
      PCI\VEN_10DE&DEV_0322
      PCI\VEN_10DE&CC_030000
      PCI\VEN_10DE&CC_0300
      PCI\VEN_10DE
      PCI\CC_030000
      PCI\CC_0300

    How the device driver is selected from these IDs is explained at =
http://support.microsoft.com/kb/279112.  I didn't read through the =
article so I don't know if it points out one gotcha that are = particularly

the OEMs make changes but forget to change the PCI IDs.  = In other words,
multiple incompatible devices claim to be the same or = compatible.  I
don't have this issue with any of my current hardware but = I have two
friends/family that have systems with OEM nvidia adapters = that claim to

customized OEM drivers.  This sounds exactly like the = problem you have
only I think both these folks are using dell systems = not asus systems.
