DESCRIPTION

       r128  is	 an  XFree86  driver for ATI Rage 128 based video
       cards.  It contains full support for 8, 15, 16 and 24  bit
       pixel depths, hardware acceleration of drawing primitives,
       hardware cursor, video modes up to 1800x1440 @ 70Hz,  dou
       blescan	modes  (e.g., 320x200 and 320x240), gamma correc
       tion at all pixel depths, a fully  programming  dot  clock
       and robust text mode restoration for VT switching.


SUPPORTED HARDWARE

       The  r128  driver  supports  all	 ATI Rage 128 based video
       cards including the Rage Fury AGP 32MB, the XPERT 128  AGP
       16MB and the XPERT 99 AGP 8MB.


CONFIGURATION DETAILS

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

       The  driver  auto-detects all device information necessary
       to initialize the card.	However,  if  you  have	 problems
       with auto-detection, you can specify:

	   VideoRam - in kilobytes
	   MemBase  - physical address of the linear framebuffer
	   IOBase   - physical address of the MMIO registers
	   ChipID   - PCI DEVICE ID

       In addition, the following driver Options are supported:

       Option "SWcursor" "boolean"
	      Selects software cursor.	The default is off.

       Option "NoAccel" "boolean"
	      Enables or disables all hardware acceleration.  The
	      default is to enable hardware acceleration.

       Option "Dac6Bit" "boolean"
	      Enables or disables the use of  6	 bits  per  color
	      component	 when  in 8 bpp mode (emulates VGA mode).
	      By default, all 8	 bits  per  color  component  are
	      used.  The default is off.

       Option "VideoKey" "integer"
	      This  overrides the default pixel value for the YUV
	      video overlay key.  The default value is undefined.

       Option "Display" "string"
	      Select  display mode for devices which support flat
	      panels. Supported modes are:

	      "FP" - use flat panel;

	      "CRT" - use cathode ray tube;

	      "Mirror" - use both FP and CRT;

	      "BIOS" - use mode as configured in the BIOS.

	      The default is FP.


       The following Options are  mostly  important  for  non-x86
       architectures:

       Option "ProgramFPRegs" "boolean"
	      Enable  or  disable  programming	of the flat panel
	      registers.  Beware that this may damage your panel,
	      so  use this at your own risk.  The default depends
	      on the device.

       Option "PanelWidth" "integer"

       Option "PanelHeight" "integer"
	      Override the flat panel dimensions in pixels.  They
	      are  used	 to  program the flat panel registers and
	      normally determined using the video card	BIOS.  If
	      the wrong dimensions are used, the system may hang.

       Option "UseFBDev" "boolean"
	      Enable or disable use of an OS-specific framebuffer
	      device  interface	 (which	 is  not supported on all
	      OSs).   See  fbdevhw(4)  for  further  information.
	      Default: off.


       The following additional Options are supported:

       Option "ShowCache" "boolean"
	      Enable  or  disable viewing offscreen cache memory.
	      A development debug option.  Default: off.
