    		  ASCENTIA 8XXN AND 9XXN DISPLAY DOES NOT WORK PROPERLY
    				  WHEN MULTITASKING WITH A DOS SHELL

    PROBLEM

    When using the DOS command  "mode bw80,50" in a DOS shell, under Windows,
    to switch the display to 50 column mode, there will be no line feeds in the
    displayed text if the user multitasks  out to Windows and then back
    to DOS shell.

    CAUSE

    The wrong version (ANSI.SYS) of the ANSI driver is loaded.

    SOLUTION

    Load Western Digital's WDANSI.SYS (to replace DOS's ANSI.SYS).

    To install WDANSI.SYS, run INSTALL.EXE from the DOS video drivers disk, and
    select "utilities" from the drivers/installation screen.

    Load the WDANSI.SYS driver in the CONFIG.SYS file (replacing ANSI.SYS).
