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

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

CONFIGURATION DETAILS
       Please refer to XF86Config(5x) for general configuration details.  This
       section only covers configuration details specific to this driver.

       The Intel 8xx family of integrated graphics chipsets has a unified mem-
       ory  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 hardware cursor is used.

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

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