DISPLAY OPTIONS FOR AT&T and OLIVETTI COMPUTERS

     The AT&T 6386 uses either the VDC400 or VDC750 display
board.  Both are supported in Windows/386.  The VDC400 has a
640x400 monochrome display and is equivalent in appearance to the
older AT&T indigenous display board.  It does not support color
except in the limited fashion described below.  To run
Windows/386 in full color choose the VDC750 during setup,
assuming you have the appropriate hardware.

     On an Olivetti M380, you should choose the OEC or OVC
display option.  Please be sure to set the OEC adapter dip
switches according to whether you have a color or monochrome
monitor.

     When using a positive video controller (PVC), be sure to
select this option during Setup.  Windows will not appear in
color but the background shading can be selected (see below).

     On both the Olivetti OEC and the VDC750 it may be possible
to operate Windows/386 using the VDC400 setup option provided the
dip switches on the display are set for CGA emulation.  Be aware
that this option is not currently supported.


WINDOWS/386 AND THE OLIVETTI/AT&T 640X400 MONOCHROME DISPLAY

     You can select one of 15 background colors (if you have a
color monitor) or shades (if you have a monochrome monitor) when
using the 640x400 monochrome display board (VDC400 or PVC setup)
by setting the background parameter to the number of the desired
color (except black) from the chart below and modifying the
corresponding entry in WIN.INI.

 0 - black       1 - blue            2 - green         3 - cyan
 4 - red         5 - magenta         6 - yellow        7 - white
 8 - grey        9 - light blue     10 - light green  11 - light cyan
12 - light red  13 - light magenta  14 - light yellow 15 - bright white

     For example, the following setting in WIN.INI gives a light
cyan background.

[MonoDisp400]
    foreground=0
    background=11

The foreground parameter is not used, nor do these settings have
any effect when running Windows/386 in full color.


WINDOWS/386 ON A ONE-MEGABYTE OLIVETTI M380 OR AT&T 6386

     Windows/386 normally requires about 1.5 megabytes of memory
to run on the M380/6386.  It is still possible to run Windows on
a one-megabyte machine by typing "win86" instead of "win386".  In
this way you can make use of the Desktop, Write, and other
applications written specifically for Windows.  However, you
cannot run any standard applications from Windows.


OLIVETTI KEYBOARD NOTES

     Some versions of the MS-DOS installable keyboard drivers
KEYBxx.COM do not function correctly when Windows is running.  In
particular, the keyboard lights (NUM LOCK, SCROLL LOCK, and CAPS
LOCK) may not indicate the correct state of their respective
keys.  In addition, SHIFT-PRT SC and PAUSE may not behave as
expected.  If KEYBxx.COM is not installed, these difficulties do
not arise.  

     Your dealer can provide you with updates to KEYBxx.COM which
will operate correctly with Windows.
