NAME
       radeon - ATI RADEON video driver

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

DESCRIPTION
       radeon is a XFree86 driver for ATI RADEON based video cards.  It contains full support for
       8, 15, 16 and 24 bit pixel depths, dual-head setup, flat panel, hardware 2D  acceleration,
       hardware  3D  acceleration  (except  R300  cards), hardware cursor, XV extension, Xinerama
       extension.

SUPPORTED HARDWARE
       The radeon driver supports PCI and AGP video cards based on the following ATI chips

       R100	   Radeon 7200

       RV100	   Radeon 7000(VE), M6

       RV200	   Radeon 7500, M7

       R200	   Radeon 8500, 9100, FireGL 8800/8700

       RV250	   Radeon 9000, M9

       R300	   Radeon 9700PRO/9700/9500PRO/9500, FireGL X1/Z1

CONFIGURATION DETAILS
       Please refer to XF86Config(5x) for general configuration details.  This section only  cov-
       ers 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  (emu-
	      lates 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 "UseFBDev" "boolean"
	      Enable  or disable use of an OS-specific framebuffer device interface (which is not
	      supported on all OSs).  See fbdevhw(4x) for further 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 "ForcePCIMode" "boolean"
	      Force to use PCI GART for DRI acceleration.
	      (used only when DRI is enabled)
	      The default is off.

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

       Option "CloneDisplay" "integer"
	      This option is only used for dual-head cards with only single screen section speci-
	      fied in the configuration file.

	      0      -- disable
	      1      -- auto-detect (default)
	      2      -- force on
	      3      -- auto-detect + 2nd head overlay
	      4      -- force on + 2nd head overlay
	      others -- auto-detect

	      disable  means  only  one  CRTC is used for both heads.  auto-detect means the sec-
	      ondary head will be driven by CRTC2 if a monitor is detected there.  force on means
	      the secondary head will be driven by CRTC2 even no monitor is detected there.  2nd-
	      head overlay means the only hardware overlay will be placed to the secondary head.

	      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

       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.

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

       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 "ForceLegacyCRT" "boolean"
	      Enable  usage  of  legacy VGA CRT display when no monitor is detected.  This can be
	      used to force the driver to work with ancient VGA monitors, such as an old mono VGA
	      monitor.	 Plugging 2 monitors into a dualhead radeon card while using this option,
	      may cause damage to one or both monitors.  off.
