SYNOPSIS

	 Driver	"neomagic"

       EndSection

DESCRIPTION
       neomagic	 is an XFree86 driver for the Neomagic graphics	chipsets found
       in many laptop computers.

SUPPORTED HARDWARE
       neomagic	supports the following chipsets:

       MagicGraph 128	 (NM2070)

       MagicGraph 128V	 (NM2090)

       MagicGraph 128ZV	 (NM2093)

       MagicGraph 128ZV+ (NM2097)

       MagicGraph 128XD	 (NM2160)

       MagicGraph 256AV	 (NM2200)

       MagicGraph 256AV+ (NM2230)

       MagicGraph 256ZX	 (NM2360)

       MagicGraph 256XL+ (NM2380)

       The driver supports depths 8, 15, 16 and	24 for all chipsets except the
       NM2070  which  does  not	 support depth 24.  All	depths are accelerated
       except for depth	24 which is only accelerated on	NM2200 and newer  mod-
       els.   All visuals are supported	in depth 8.  TrueColor and DirectColor
       visuals are supported in	the other depths.

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

       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 "PCIBurst" "boolean"
	      Disable or enable	PCI burst modes.  Default: enabled.

       Option "Rotate" "CW"

       Option "Rotate" "CCW"
	      Rotate  the display clockwise or counterclockwise.  This mode is
	      unaccelerated.  Default: no rotation.

       Option "ShadowFB" "boolean"
	      Enable or	disable	use of the shadow framebuffer layer.  Default:
	      off.

       Option "OverlayMem" "integer"
	      Reserve  the  given  amount  of memory (in bytes)	for the	XVideo
	      overlay.	On boards with limited memory, display of large	XVideo
	      buffers  might fail due to insufficient available	memory.	 Using
	      this option solves the problem at	the expense  of	 reducing  the
	      memory  available	 for  other  operations.   For full-resolution
	      DVDs, 829440 bytes (720x576x2) are necessary.

       Note
       On some laptops using the 2160 chipset (MagicGraph 128XD) the following
       options are needed to avoid a lock-up of	the graphic engine:
	   Option "XaaNoScanlineImageWriteRect"
	   Option "XaaNoScanlineCPUToScreenColorExpandFill"
