    			Ascentia 950N P/120 SimulSCAN Mode

    PROBLEM

    When the "Font Expand" option in system setup is disabled, and the Ascentia
    950N system is operating in SimulSCAN mode, any program which uses a
    640x480 display mode will be displayed in the upper left hand corner of the
    CRT; the same program will be displayed in the center of the LCD panel.
    An example of this would be the introductory screens for Windows 3.X and
    Windows 95, or either of these operating systems running 640x480 display
    drivers.

    CAUSE

    The Cirrus 7543 is operating as designed, in order to maintain compatibility
    with older software.

    SOLUTION

    Do the following:

    1. Enable "Font Expand" in system setup.

    2. Use 800x600 video drivers.  The symptom will still occur, but will correct
       itself after the introductory graphic has been displayed.
