       i810 - Intel 8xx integrated graphics chipsets

       Section "Device"
	 Identifier "devname"
	 Driver "i810"

       i810  is  an  XFree86  driver for Intel integrated graphics chipsets.  The driver supports
       depths 8, 15, 16 and 24.  All visual types are supported in depth  8,  other  depths  only
       support	TrueColor.   The driver supports hardware accelerated 3D via the Direct Rendering
       Infrastructure (DRI), but only in depth 16 for the i810/i815 and  depths  16  and  24  for
       later chipsets.

       i810  supports  the  i810,  i810-DC100,	i810e,	i815,  830M, 845G, 852GM, 855GM, and 865G

       Please refer to XF86Config(5x) for general configuration details.  This section only  cov-
       ers configuration details specific to this driver.

       The Intel 8xx family of integrated graphics chipsets has a unified memory architecture and
       uses system memory for video ram.  By default 8 Megabytes of system memory  are	used  for
       graphics.   For the 830M and later, the default is 8 Megabytes when DRI is not enabled and
       32 Megabytes with DRI is enabled.  This amount may be changed with the VideoRam	entry  in
       the  config  file  Device  section.   It may be set to any reasonable value up to 64MB for
       older chipsets or 128MB for newer chipets.  Note that increasing this  value  will  reduce
       the amount of system memory available for other applications.

       The following driver Options are supported

       Option "NoAccel" "boolean"
	      Disable or enable acceleration.  Default: acceleration is enabled.

       Option "SWCursor" "boolean"
	      Disable or enable software cursor.  Default: software cursor is disable and a hard-
	      ware cursor is used.

       Option "ColorKey" "integer"
	      This sets the default pixel value for the YUV video overlay  key.   Default:  unde-

       Option "CacheLines" "integer"
	      This  allows the user to change the amount of graphics memory used for 2D accelera-
	      tion and video.  Decreasing this amount leaves more for 3D textures.  Increasing it
	      can  improve  2D performance at the expense of 3D performance.  Default: 256 to 768
	      depending on the resolution and depth.
