DESCRIPTION

       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.


SUPPORTED HARDWARE

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



CONFIGURATION DETAILS

       Please refer to XF86Config(5)  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	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 Vide
       oRam 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: accelera
	      tion is enabled.

       Option "SWCursor" "boolean"
	      Disable  or enable software cursor.  Default: soft
	      ware 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 graph
	      ics  memory  used	 for  2D  acceleration 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.
