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"
