   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 =
hardware that is responsible for identifying both itself and the devices =
with which it is compatible.  On Windows XP open the device manager, =
select the device of interest, right click, pick Properties, then select =
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
relevant to OEM devices like nvidia display adapters.  The = gotcha is that
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
be compatible with the nvidia drivers but don't work = unless you use
customized OEM drivers.  This sounds exactly like the = problem you have
only I think both these folks are using dell systems = not asus systems.

  That will teach a lesson . I am concerned that after 2 YEARS it =
