DESCRIPTION

       i810  is	 an  XFree86  driver for the Intel i810 family of
       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  hard
       ware  accelerated  3D via the Direct Rendering Infrastruc
       ture (DRI), but only in depth 16.


SUPPORTED HARDWARE

       i810  supports  the  i810,  i810-DC100,	i810e  and   i815
       chipsets.



CONFIGURATION DETAILS

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

       The i810 has a unified memory architecture and uses system
       memory for video ram.  By default 8  Megabytes  of  system
       memory  are used for graphics.  This amount may be changed
       with the VideoRam entry in the config file Device section.
       It  may	be  set	 to  any  power	 of  two between 4 and 32
       Megabytes inclusive to allow the	 user  to  customize  the
       balance	between	 main  memory  usage and graphics perfor
       mance.  Too little memory reserved for graphics can result
       in  decreased 3D and 2D graphics performance and features.

       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.
