						Readme.txt for Windows CE release
						---------------------------------

Features:
========

* DirectDraw based Display Driver: The driver is based on DDGPE model to 
  support various DirectDraw features in WinCE 3.00 and WCEfA 3.00 such as 
  Overlays, Flip, etc.

* Resolution: The resolution is determined automatic on the panel size. So for
  a 640x480 panel, the resolution will be 640x480 and for a 1024x768 panel the
  resolution will be 1024x768. Only the color depth is variable. It defaults to
  8-bpp but can be changed in the registry (see below).

* DualApp Mode: The desktop size can be extended to two different monitors. 
  This mode is specified in the registry.

* Virtual Mode: The desktop size can be larger than the panel size. For example,
  you can have a panning 1024x768 mode on a 800x600 panel. This is specified in
  the registry.

* AutoPC and TruckPC modes: Special modes are availahle for AutoPC using Toshiba
  panel and TruckPC using Planar panel. These modes are specified in the
  registry.

* SVPMI files: The modes are hard coded into the driver, but with the use of
  industry standard SVPMI (Super VGA Protected Mode Interface) files you can
  override the registry settings. Silicon Motion Inc. can provide an utility to
  create a SVPMI file which can be included into the Windows CE image to
  override any mode settings.

Configuration:
=============

The platform directory needs to be updated in order to compile our driver and
set the various options. Here is a complete list:

* SMI source code: The SMI source code should reside in the
  %_TARGETPLATROOT%\Drivers\Display directory in a subdirectory called SMI. The
  DIRS file in the %_TARGETPLATROOT%\Drivers\Display directory should include
  this new directory in the DIRS list.

* The %_TGTPLAT%.BAT file in the %_TARGETPLATROOT% directory should have the
  following extra options:

	SET SMI=1
	SET AUTOPC=1	;if you are compiling for an AutoPC or TruckPC platform

* Change the PLATFORM.BIB in the %_TARGETPLATROOT%\Files directory like this:

    IF SMI !
      ; all other instances of the ddi.dll file
    ENDIF
    IF SMI
      ddi.dll $(_FLATRELEASEDIR)\ddi_smi.dll NK SH
    ENDIF

    If you are using a SVPMI file, copy it into the %_TARGETPLATROOT%\Files
    directory and add the following lines at the end of the PLATFORM.BIB file
    (this sample assumes a SVPMI file with the name sm710.pmi):

    FILES
    IF SMI
      sm710.pmi $(_FLATRELEASEDIR)\sm710.pmi NK SH
    ENDIF

* Change the PLATFORM.REG in the %_TARGETPLATROOT%\Files directory to include
  any options you want.

Registry options:
================

The following registry options can be defined in the PLATFORM.REG file located
in the %_TARGETPLATROOT%\Files directory:

[HKEY_LOCAL_MACHINE\Drivers\Display\SMI]
	"Bpp"			=	dword:{8,10,18}
	"AutoPC"		=	dword:1
	"TruckPC"		=	dword:1
	"VirtualResX"	=	dword:{any value in hex}
	"VirtualResY"	=	dword:{any value in hex}
	"PMI"			=	"{location of PMI file}"
	"DualApp"       = 	dword:1
	"P350"       	= 	dword:1

* Bpp: This parameter specifies the pixel depth. By default it is 8. Remember
  that all values are in hex, so 16-bpp is "10" and 24-bpp is "18".

* AutoPC: Turn *ONLY* this parameter to 1 for AutoPC systems that use the
  Toshiba panel. It will switch to 400x234 in 8-bpp mode.

* TruckPC: Turn *ONLY* this parameter to 1 for TruckPC systems that use the
  Planar panel. It will switch to 320x80 in 8-bpp mode.

* VirtualResX & VirtualResY: To specify a virtual (panning) resolution larger
  than the panel. Remember that the values are in hex!

* PMI: Use this variable to specifiy the location and name of the SVPMI file,
  for example, "\\WINDOWS\\SM710.PMI". Be sure to put the "\\WINDOWS\\" in
  front of the name; this is where the flies are loaded inside the image.

* DualApp: Turn this parameter to 1 for DualApp mode support. This extends the desktop
  size to two different monitors.

* P350: Turn this parameter to 1 for special SHARP 640x350 panel. 
  It will switch to 640x350 in 16-bpp mode.
