these new modules.


STRETCH for Windows.

To use STRETCH under Windows, to extend conventional
memory into the VGA range, you must load STRETCH before
you start Windows.  Then go to a DOS prompt once
Windows has started and type STRETCH.  Conventional
memory will be extended to 704K if you are using the
B000-B7FF range and to 736K if the B000-B7FF Monochrome
region is available.

Note that when Windows starts you may receive a Warning
from STRETCH about a graphics program starting while
STRETCH is active.  You can select "C" to continue
safely.  To prevent this message either turn STRETCH
OFF before starting Windows, or start Windows with the
"WIN :" (WIN-space-colon) command.

To ensure that you can get a 736K DOS Box you can run
Customize in Custom mode and select "No" to the "Create
Upper memory in the Monochrome" region prompt.

STRETCH is also in the CUSTOMIZ.INF file.  You can
safely remove the *STRETCH entry from the CUSTOMIZ.INF
file and re-Customize, although you don't have to.
Note that when STRETCH is loaded into upper memory it
automatically is set to the OFF condition and you will
need a STRETCH ON command to turn STRETCH ON.



CACHECLK Windows cache monitor.

To use the Windows Cloaked Cache Monitor program simply
double click on the CACHECLK.EXE entry in the Netroom
directory, or add CACHECLK.EXE to your Desktop.

When the CACHECLK window appears you can Select the
"Maintain window topmost" check box, and the Cache
monitor will stay as the top most window at all times.

You may also manually Flush the cache by clicking the
"Flush Cache Now" button, and enable or disable write-
caching by selecting the "Enable write caching" check
box.

The bar graphs at the top of the window display the
instant read and write hit ratio.  This is the percent
of the reads or writes found in the cache since the
last bar was drawn in the graph.  New bars are drawn
every two seconds during disk activity.  The numeric
value below the bar graph is the TOTAL read or write
hit ratio since the cache was started.

If you re-size the cache, all data currently in the
cache is flushed to disk and the counters are re-set.
So if your Windows size for the cache is different from
the non Windows size the cache will reset each time you
load Windows.  If you load Windows several times a day
we recommend that you set the two sizes the same this
will allow Windows to load faster.


SAVERCLK Windows configuration utility

To use the Windows Cloaked Screen Saver configuration
utility simply double click on the SAVERCLK.EXE entry
in the Netroom directory, or add SAVERCLK.EXE to your
Desktop.

When the SAVERCLK window appears you can set the
various screen saver parameters, load new modules and
configure the individual saver modules.  The initial
SAVERCLK Window contains a selection to enable or
disable the saver, a duration in seconds of inactivity
until the saver blanks the screen, and the Screen Saver
HOT-KEY.

The Test Button allows you to test the currently
selected module, and the Current Module field allows
you to change the currently loaded graphics module.  In
Windows you may only load modules that are the same or
smaller than the saver module you had loaded when
Windows started.  Thus some of your modules may not
show up in the Current Module selector box.

The Options button brings up a dialog box that lets you
configure the characteristics of the particular screen
saver module selected.  This operates in the same
manner as the Netroom SETUP program for the screen
saver operation.


The WINMEM Windows buffers program.

Windows has an undocumented parameter that allows each
DOS Box to have its own, separate, upper memory region.
This allows you to have different devices and TSRs
loaded into upper memory in each DOS Box.  To activate
this feature place the parameter "LocalLoadhigh=ON" in
the [386Enh] section of your SYSTEM.INI.

This will, however, force Windows to load it's
translation buffers into Conventional memory.  To get
around this problem Place the WINMEM.EXE file at the
end of your AUTOEXEC.BAT, specifying how many K to
reserve in upper memory for Windows.  For example, the
command:

     WINMEM 36

will reserve 36K for Windows' use in upper memory even
if you have LocalLoadhigh=ON.

Next, run Customize to load this TSR into upper memory.
Now when you run Windows you can use the DOS 5/6
LOADHIGH (LH) command to place device drivers and TSRs
in upper memory.  To load device drivers high use the
command "LH DEVLOAD device-driver-command"  See the
Netroom documentation for information on DEVLOAD.

Note however that Windows does not check for TSRs
loaded in upper memory when you close a DOS Box and so
you could lose data stored in TSRs that you loaded high
in the DOS Box, if you EXIT the DOS box without saving
the data.

NOTE: This feature is for advanced users only, as
incorrect use of instanced upper memory blocks may
result in loss of data.  Also, WINMEM is not useful and
is not needed if you are not using LocalLoadhigh=ON.

LocalLoadhigh=ON will only operate correctly if prior
to starting Windows you have at least one upper memory
region with at least 12K free in it.  If you do not you
may receive an error stating that Windows "has
insufficient address space to start."  If you get this
message you cannot use LocalLoadhigh=On, so remove this
line from your SYSTEM.INI
