          | MicroStation PC 5.0 Driver (DOS 386 Protected Mode 5.0) |
          ===========================================================

This driver supports MicroStation 5.0 for the DOS 386 protected mode environment
. The first time this driver is used, it will present the user with a menu of
all available resolution modes. One must be selected, and then a configuration
file will be created that the driver will use for subsequent MicroStation
sessions.

To re-configure the driver, erase the files \USTAT50\DRIVERS\*.CFG and run the
MicroStation 5.0 USTATION.bat file again.

Supported modes for S3 hardware configurations include:

Mode    Resolution      Colors
  0     640 x 480       256 colors
  1     800 x 600       16 colors
  2     800 x 600       256 colors
  3     1024 x 768      16 colors
  4     1024 x 768      256 colors
  5     1152 x 864      256 colors
  6     1280 x 1024     16 colors
  7     1280 x 1024     256 colors
  8     1600 x 1200     256 colors

Please note that not all resolution modes may be available.


MicroStation PC Driver Installation
-----------------------------------
1. Now, the drivers are located in a directory ( e.g. C:\TRIODRV\PMUSTAT5 ),
   after the steps of Section " Decompressing Drivers " in Chapter " Software
   Installation " of manual completed.

2. Copy the following files to the \USTAT50\DRIVERS directory from
   C:\TRIODRV\PMUSTAT5:

   MGL5S3.EXP
   MGL5S3.MA
   MGL5S3.MGL

3. Change the current directory to the \USTAT50 sub-directory, or the one that
   contains the MicroStation application.

4. Run the USCONFIG program to select the new device driver.
   a. Select Generate for:  "DOS"
   b. Select "Display Adapters" entry.
   c. Select Right Screen Graphics Adapter "MGL5S3 v1.XX for  S3 Accelerators"
      option.
   d. Select Left Screen Graphics Adapter "as needed"
   e. Select Swap Screen Status  "Y" or "N" .
   f. Select "Exit and Save".
   g  Run the USTATION.bat from the \USTAT50 subdirectory.
   h. Select the desired mode from the list of supported resolutions.
   i. Respond "Y" or "N" to Use Hardware scrolling.
      By accepting the default of "Yes", scrolling will be faster but thick
      diagonal lines will display notches after the scroll. (Selecting the
      UPDATE icon from the Main Palette will refresh the display.)
   j. MicroStation 5.0 will now be launched.

This driver will work with a Hercules-compatible card as the second graphics
device.

SWAP screen capabilities are supported if a 256 color mode is configured. If the
initialization code is unable to determine which mode to use, it will always
default to the 640 x 480 x 256 color mode. The driver will exit if it is not
able to find an S3-based graphics card.
