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 0x1E.

       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 fur-
	      ther information.
	      The default is off.

       Option "AGPMode" "integer"
	      Set AGP data transfer rate.  (used only when DRI is enabled)
	      1      -- x1 (default)
	      2      -- x2
	      4      -- x4
	      others -- invalid

       Option "AGPFastWrite" "boolean"
	      Enable AGP fast write.
	      (used only when DRI is enabled)
	      The default is off.

       Option "BusType" "string"
	      Used to replace previous ForcePCIMode option.  Should only be used when driver's bus detection is incorrect or you want to  force  a
	      AGP card to PCI mode. Should NEVER force a PCI card to AGP bus.
	      PCI    -- PCI bus
	      AGP    -- AGP bus
	      PCIE   -- PCI Express (falls back to PCI at present)
	      (used only when DRI is enabled)
	      The default is auto detect.

       Option "ForcePCIMode" "boolean"
	      Force  to  use PCI GART for DRI acceleration.  This option is deprecated in favor of the BusType option above and will be removed in
	      the next release.

       Option "DDCMode" "boolean"
	      Force to use the modes queried from the connected monitor.
	      The default is off.

       Option "DisplayPriority" "string"
	      Used to prevent flickering or tearing problem caused by display buffer underflow.
	      AUTO   -- Driver calculated (default).
	      BIOS   -- Remain unchanged from BIOS setting.
			Use this if the calculation is not correct
			for your card.
	      HIGH   -- Force to the highest priority.
			Use this if you have problem with above options.
			This may affect performence slightly.
	      The default value is AUTO.

       Option "MonitorLayout" "string"
	      This option is used to overwrite the detected monitor types.  This is only required when driver makes a false detection.	The possi-
	      ble monitor types are:
	      NONE   -- Not connected
	      CRT    -- Analog CRT monitor
	      TMDS   -- Desktop flat panel
	      LVDS   -- Laptop flat panel
	      This option can be used in following format:
	      Option "MonitorLayout" "[type on primary], [type on secondary]"
	      For example, Option "MonitorLayout" "CRT, TMDS"

	      Primary/Secondary head for dual-head cards:
	      (when only one port is used, it will be treated as the primary regardless)
	      Primary head:
	      DVI port on DVI+VGA cards
	      LCD output on laptops
	      Internal TMDS prot on DVI+DVI cards
	      Secondary head:
	      VGA port on DVI+VGA cards
	      VGA port on laptops
	      External TMDS port on DVI+DVI cards

	      The default value is undefined.

       Option "CloneMode" "string"
	      Set  the	first  mode  for the secondary head.  It can be different from the modes used for the primary head. If you don't have this
	      line while clone is on, the modes specified for the primary head will be used for the secondary head.
	      For example, Option "CloneMode" "1024x768"
	      The default value is undefined.

       Option "CloneHSync" "string"
	      Set the horizontal sync range for the secondary  monitor.  It is not required if a DDC-capable monitor is connected.
	      For example, Option "CloneHSync" "30.0-86.0"
	      The default value is undefined.

       Option "CloneVRefresh" "string"
	      Set the vertical refresh range for the secondary monitor.  It is not required if a DDC-capable monitor is connected.
	      For example, Option "CloneVRefresh" "50.0-120.0"
	      The default value is undefined.

       Option "OverlayOnCRTC2" "boolean"
	      Force hardware overlay to clone head.
	      The default value is off.

       Option "IgnoreEDID" "boolean"
	      Do not use EDID data for mode validation, but DDC is still used for monitor detection. This is different from NoDDC option.
	      The default value is off.

       Option "PanelSize" "string"
	      Should only be used when driver cannot detect the correct panel size.  Apply to both desktop (TMDS) and laptop (LVDS)  digital  pan-
	      els.   When a valid panel size is specified, the timings collected from DDC and BIOS will not be used. If you have a panel with tim-
	      ings different from that of a standard VESA mode, you have to provide this information through the Modeline.
	      For example, Option "PanelSize" "1400x1050"
	      The default value is none.

       Option "PanelOff" "boolean"
	      Disable panel output. Only used when clone is enabled.
	      The default value is off.

       Option "EnablePageFlip" "boolean"
	      Enable page flipping for 3D acceleration. This will increase performance but not work  correctly	in  some  rare	cases,	hence  the
	      default is off.

       Option "ForceMinDotClock" "frequency"
	      Override	minimum  dot  clock. Some Radeon BIOSes report a minimum dot clock unsuitable (too high) for use with television sets even
	      when they actually can produce lower dot clocks. If this is the case you can override the value here.  Note that using  this  option
	      may  damage  your  hardware.  You have been warned. The frequency parameter may be specified as a float value with standard suffixes
	      like "k", "kHz", "M", "MHz".
