DESCRIPTION

       neomagic  is an Xorg 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
       models.    All  visuals  are  supported  in  depth  8.   TrueColor  and
       DirectColor visuals are supported in the other depths.

CONFIGURATION DETAILS

       Please refer to xorg.conf(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"
