NAME
       nsc - Nsc video driver

SYNOPSIS
       Section "Device"
	 Identifier "devname"
	 Driver	"nsc"
	 ...
       EndSection

DESCRIPTION
       nsc  is	an  XFree86 driver for National	Semiconductors GEODE processor
       family.	It uses	the DURANGO kit	provided  by  National	Semiconductor.
       The  driver  is	accelerated,  and  provides  support for the following
       framebuffer depths: 8, 16 and 24.

SUPPORTED HARDWARE
       The nsc driver supports GXLV (5530 companion chip), SC1200, SC1400  and
       GX2 (5535 companion chip).

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

       The driver will auto-detect the amount of video memory present for  all
       chips.  If  the	amount	of  memory is detected incorrectly, the	actual
       amount of video memory should be	specified with a VideoRam entry	in the
       config file "Device" section.

       The following driver Options are	supported:

       Option "SWCursor" "boolean"
	      Enable or	disable	the SW cursor.	Default: off.

       Option "HWCursor" "boolean"
	      Enable or	disable	the HW cursor.	Default: on.

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

       Option "NoCompression" "boolean"
	      Disable or enable	compression.  Default: compression is enabled.

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

       Option "Rotate" "CW"
	      Rotate the display clockwise. This mode  is  unaccelerated,  and
	      uses the Shadow Frame Buffer layer.  Default: no rotation.

       Option "Rotate" "CCW"
	      Rotate the display counterclockwise. This	mode is	unaccelerated,
	      and uses the Shadow Frame	Buffer layer.  Default:	no rotation.

       Option "FlatPanel" "boolean"
	      This enables the FlatPanel display unit. The  FlatPanel  depends
	      on  the  BIOS  to	do the Panel h/w initialization.  In GX2 based
	      platforms	with TFT part Flatpanel	is enabled, and	on CRT part is
	      disabled.	 Default: off.

       Option "OSMImageBuffers"	"integer"
	      This sets	the number of scanline buffers to be allocated in off-
	      screen memory for	acceleration. This can take any	value  0  will
	      disable  the  allocation.	 Disabled if cannot allocate requested
	      scanline memory.	Default: 20.

       Option "ColorKey" "integer"
	      This sets	the default pixel value	for the	YUV video overlay key.
	      Default: 0.

       The following Options are supported only	on SC1200 based	platforms:

       Option "TV" "PAL-768x576"
	      Selects  the PAL TV display mode 768x576 and the depth is	forced
	      to 16 bpp.  Default: no TV.

       Option "TV" "PAL-720x576"
	      Selects the PAL TV display mode 720x576 and the depth is	forced
	      to 16 bpp.  Default: no TV.

       Option "TV" "NTSC-720x480"
	      Selects the NTSC TV display mode 720x480 and the depth is	forced
	      to 16 bpp.  Default: no TV.

       Option "TV" "NTSC-640x480"
	      Selects the NTSC TV display mode 640x480 and the depth is	forced
	      to 16 bpp.  Default: no TV.

       Option "TV_Output" "COMPOSITE"
	      The  selected  TV	 mode  output  is  coded for Composite signal.
	      Default: no TV.

       Option "TV_Output" "SVIDEO"
	      The  selected  TV	 mode  output  is  coded  for  SVIDEO  signal.
	      Default: no TV.
