SMARTDRIVE, RAMDRIVE, AND THE AT&T 6300 PLUS

     The SMARTDrive and RAMDrive programs contain an additional
option allowing the 384Kb of upper extended memory normally
assigned to Simul-Task to be used as a disk cache or ramdrive if
the 6300 PLUS is being used strictly as an MS-DOS machine.  Use
the following command line in CONFIG.SYS

        device=[drive:][path]smartdrv.sys NNN /u

to obtain NNN kilobytes of memory for SMARTDrive.  NNN must be
between 256 and 384.  Similarly, the command 

        device=[drive:][path]ramdrive.sys NNN /u 

will install the RAMDrive into upper extended memory.  In this
case, NNN can be smaller than 256 but should not exceed 384.


MICROSOFT EXCEL AND THE OLIVETTI/AT&T 640x400 DEB OR EGC

     To use this display (known variously as the Display
Enhancement Board or DEB, and the Extended Graphics Color Board
or EGC) with Microsoft Excel, you must install the MS-DOS device 
driver DEDRIVER.DEV (or DEDRIVE.DEV).  The driver is on the disk
accompanying the DEB (EGC) hardware.  Copy the file to an
appropriate drive and directory, add the entry

    device=[drive:][path]dedriver.dev (or dedrive.dev)

to your CONFIG.SYS file, and reboot.

     Note that some old versions of this driver may not work
properly on the AT&T 6310 or Olivetti M28.  The usual symptom is
no mouse cursor when Microsoft Excel is run.  See your dealer or 
call the AT&T support hotline for assistance.

     If you are using the DEB (EGC) board in full color (you
chose the Olivetti/AT&T 640x400 DEB option during Setup), you may
set the mouse cursor color (or shading, if you have a monochrome
display) as it appears against its background by editing the
appropriate entry in WIN.INI.  (You will notice that the mouse
cursor maintains a contrasting color as it is moved from one
color on the screen to another.)   The sample WIN.INI entry shown
below selects a blue cursor against white or black and the
default values against any other color.

[ColorDisp400]
CCBlack=1       ; cursor is blue against black
CCRed=11        ; cursor is light cyan against red
CCGreen=13      ; cursor is light magenta against green
CCYellow=9      ; cursor is light blue against yellow
CCBlue=14       ; cursor is yellow against light blue
CCMagenta=10    ; cursor is light green against magenta
CCCyan=12       ; cursor is light red against cyan
CCWhite=1       ; cursor is blue against white

     After you have run Microsoft Excel for the first time, default
entries are made in win.ini for you.  You can then modify the
cursor contrast colors according to the following table:

 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


MICROSOFT EXCEL 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 standard 640x400 monochrome display board by setting
the background parameter to the number of the desired color
(except black) from the chart above and modifying the
corresponding entry in WIN.INI.  Similarly, if you have the
Olivetti/AT&T 640x400 color display (often called the DEB or EGC)
and a color (or monochrome) monitor (and you have installed the
MS-DOS device driver DEDRIVER.DEV (or DEDRIVE.DEV)), but you
selected the standard monochrome display during Setup, you can
still have foreground and background colors (or shades) by
setting the foreground and background parameters using the color
chart above.  These settings have no effect when the DEB (EGC) is
being used in full color in Microsoft Excel. 

     For example, the following setting in WIN.INI gives a light
cyan background if you use the monochrome display board and
produces red text on a light cyan background if the DEB is being
used.

[MonoDisp400]
    foreground=4
    background=11


MICROSOFT EXCEL AND THE OLIVETTI/AT&T KEYBOARD MOUSE

     The settings shown below in WIN.INI are read by the keyboard
mouse when Microsoft Excel is run:

[Mouse]
use=1
buttons=2
exit=1

If you have a three-button mouse, change the buttons parameter
from 2 to 3.  If the mouse is not being used, set use=0 to remove
the mouse cursor from the screen.  Finally, if the MS-DOS program
MOUSE.COM, which is supplied with this mouse, is not loaded
before Microsoft Excel is run, the mouse will return to normal 
keybased mode upon exit from Microsoft Excel to MS-DOS.  You can 
disable the arrow key action normally produced when moving the mouse 
by setting exit=0.  The left, center, and right buttons will still
function as usual.

     The keyboard mouse may not perform correctly on the AT&T
6310 with a model 302 keyboard if any of the following keys are
active (key light is on): Num Lock, Scroll Lock, or Caps Lock. 
Although not a Microsoft Excels-related problem, it can cause 
difficulty in using Microsoft Excel.  The usual symptom is that 
the mouse behaves as if it were in key-based mode, and the problem 
occurs if any of the above keys are active when you initially run 
Microsoft Excel. You can avoid this problem by deactivating these 
keys before you run Microsoft Excel.
