DESCRIPTION

     neomagic is an XFree86 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 XF86Config(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

XFree86                   Version 4.5.0                         1

NEOMAGIC(4)         UNIX Programmer's Manual          NEOMAGIC(4)

          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"
