  1.  Information for W32 Chipset Users

  XF86_W32 is basically XF86_SVGA with the drawing code completely
  replaced with one based on X11R6's mi/cfb code and modified for the
  ET4000/W32 series.  Even though it accepts the same keywords as
  XF86_SVGA, those not applicable to the ET4000/W32 series are silently
  ignored; e.g., the keyword "SpeedUp" is a no-op.  The server currently
  supports the w32, w32i, and w32p chips.  For a complete list, see the
  sign-on message printed by XF86_W32.  The server supports only 8bpp
  operation at present.

  Just as with XF86_SVGA, you can specify a virtual world that has a
  width that is a multiple of four.  The size of the virtual world is
  constrained by the amount of the available video RAM.  XF86_W32 can
  use more than 1 M of video RAM, but it reserves 1 K for internal use.
  If you have 1 M, XF86_W32 will say you have 1023 K, and you get to
  specify the virtual world as 1152x900, but not 1152x910.

  The current maximum clock is set to 86 MHz, because this is what the
  Tseng databooks say.

  If you have problems with the server.  Try the following things:

     o  Take out the Hercules monochrome adapter, if you have one.  Many
        configurations of the ET4000/W32 series do not allow one in the
        system.

     o  Get a motherboard with its local bus running at 33 MHz.  Many,
        if not all, ET4000/W32 boards will surely behave in a funny way
        on a 50-MHz bus.  You may have to use a wait state or two, but
        first try without any.

  Note that the built-in power saver (for a "green" monitor) has not
  been tested.  Also do not expect it to work on a board without a
  w32p_rev_c or later chip.


  2.  Acknowledgments

  Jerry J. Shekhel (jerry@msi.com) gave me the 1-M Mirage ET4000/W32 VLB
  board on which the initial development (X_W32) was done.

  X11R6 and the XFree86 Project provide the base code for XF86_W32.

  Hercules Computer Technology Inc. lent me a 2-M Hercules Dynamite Pro
  VLB board for the development that led to XF86_W32.

  Numerous testers have given me feedback for X_W32 and later XF86_W32.
  I apologize for my failure to keep track of the people who tested
  X_W32, but the names of the people involved with the XF86_W32 testing
  are listed below:
