gvid_no_claim_dev(5)						File Formats Manual					      gvid_no_claim_dev(5)

NAME

       gvid_no_claim_dev - PCI Vendor/Device ID that the gvid graphics driver will not claim

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
       Specific to the device you wish to prevent from claiming.

DESCRIPTION

       This tunable specifies the PCI Vendor ID and/or Device ID of a graphics device that the HP graphics driver should not claim.

       The  graphics driver was designed to be a general purpose driver for all PCI graphics cards.  As a result, the driver will attempt to claim
       any PCI graphics display device found on the system.  This can be a problem for graphics device developers  who	need  their  own  graphics
       driver to claim their own graphics device.

       The  value  of will specify a PCI Vendor ID and/or Device ID of a graphics card that the gvid graphics driver should not claim.	It is a 32
       bit number, with the upper 16 bits containing the PCI Vendor ID and the lower 16 bits containing the PCI Device ID.  Either the	Vendor	ID
       or Device ID can use a wildcard value of

       For  example,  if  is  set to the value the driver will ignore graphics devices with a PCI Vendor ID of and a Device ID of If is set to the
       driver will not claim any graphics cards with a Vendor ID of regardless of the Device ID.

   Who Is Expected to Change This Tunable?
       Anyone who wishes the graphics driver to ignore a specific graphics device.  This will typically be  someone  writing  their  own  graphics
       driver for their own hardware.

   Restrictions on Changing
       Changes to this tunable take effect at the next reboot.

   What Other Tunables Should Be Changed at the Same Time?
       None.

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
