Setup and Utilities:
--------------------

- Setup program v1.70

  Running the SETUP program to select a monitor is highly recommended,
  particularly if your monitor does not support all the resolutions that
  the board supports.
  Note that if you select a monitor through the new Windows Monitor
  Program included with PowerDesk 2.1, the selection is also valid for
  AutoCAD DOS driver, so the DOS Setup program does not need to be used.
  
- VESA driver v2.03

  Even though your board can support at least 1280 X 1024 resolution, the
  VESA driver is limited to 1024 X 768. See README.SET file for a complete
  list of VESA modes supported.

AutoCAD Driver v1.70:
---------------------

- AutoCAD R13 Support

  AutoCAD R13 is supported as of v1.70. Dynaview/3D also works
  with R13 with exception that it cannot render the newly introduced
  3D solids.

- More modes

  The mode selection mechanism has changed as of v1.50. It is now possible
  to have smooth animation in DynaView/2D even in 16 and 24 bit modes.

- DynaView/3D

  DynaView/3D is supported on the Impression family including the
  Impression Plus and Impression Lite. Support for the Lite is limited
  to wireframe during animation sequences. Keep in mind that 3D solids
  in R13 are not supported by Dynaview/3D.

- 3D Studio

  Autodesk supports the MGA in their 3D Studio 3.0 inline driver.
  This is an Autodesk driver and is available from Autodesk on
  Compuserve and also in the 3D Studio box.

- AutoCAD for Windows:

  The AutoCAD for Windows driver is available on the PowerDesk disks. It
  accelerates AutoCAD for Windows Rel 12 by talking directly to the MGA
  hardware, and comes with a Bird's Eye / Spy Glass viewer callable
  from the Autodesk DSVIEWER command.

- DynaView/3D for Windows:

  This application (like AutoCAD for Windows) is available on the PowerDesk
  disks. It allows real-time manipulation of 3D models created under 
  AutoCAD for Windows. Note that if the current windows mode,as selected via
  the MGA control panel, is not a 3D mode then DynaView/3D will be limited
  to wireframe.

MicroStation Driver v2.00:
--------------------------

- MicroStation 5.0 Only

  MicroStation drivers v2.00 and higher support MicroStation 5.0 only.
  Contact our technical support staff if you require our
  MicroStation 4.0 driver.

- New features (v2.00 or higher)
  
  Hardware assisted 3D rendering (for Impression models)
  Window management (backing store)
  Dynamic Link Module (DLM)
  New configuration screen

- Multiple Configurations

  The driver also supports single screen (with or without swap screen), dual 
  screen and Windows Connection (single or dual screen).  

  Note that if you use the MicroStation Windows Connection with a dual-MGA
  configuration, the Windows Connection driver must run on the MGA board
  which has its VGA enabled.
