MagnaRAM 2.0 General Information and Troubleshooting
Quarterdeck Technical Note #315 Filename: MAGNARM2.TEC

Subject: This technical note provides general information and
troubleshooting tips for MagnaRAM 2.0. For information
on MagnaRAM 1.0, refer to the Quarterdeck Technical Note
#300, "MAGNARAM.TEC 1.0 General Information".
General MagnaRAM 2.0 information:
Quarterdeck's MagnaRAM is an easily configurable utility designed
to increase your available memory, performance and multitasking
capabilities within Windows 3.1x, Windows for WorkGroups, and
Windows 95. MagnaRAM provides you with more available memory and
performance by using powerful memory multiplying technology.
MagnaRAM's memory multiplying techniques provide:
* significant amounts of additional Windows memory for your
programs by compressing data, both in RAM memory and on your
hard disk.
* performance benefits to your system by minimizing the use of
slower virtual memory. The more you use your high-speed
system RAM, the less you must access the much slower virtual
memory.
System Requirements:
* An IBM or IBM-compatible PC or PS/2 with 386 or higher
processor
* 4 MB of RAM. Performance improves with the amount of
installed memory
* Windows 95, or Windows 3.1x / Windows for WorkGroups
running in 386 Enhanced mode
* MS or IBM-DOS 3.1 or later, or Novell DOS
* Windows Virtual Memory feature must be enabled (recommended
Permanent swap file).
General Troubleshooting Issues:
1. Q. Is MagnaRAM compatible with disk compression programs?
A. MagnaRAM is compatible with disk compression programs
such as Stac Electronics' Stacker and Microsoft's
DoubleSpace and DriveSpace. MagnaRAM does not interact
directly with your hard disk, or with disk compression
programs -- it lets Windows swap all data to the disk.
2. Q. Where is the Uninstall icon that is documented in the
manual?
A. Some revisions of the MagnaRAM User Guid make an
erroneous reference to an uninstall icon in the MagnaRAM
folder for Windows 95. On Windows 95 systems, use the
Add/Remove Programs feature located in the Control Panel.
On Windows 3.1x / Windows for WorkGroups systems, use the
MagnaRAM uninstall icon located in the MagnaRAM group.
3. Q. I have deleted MagnaRAM, but I can't reinstall it. My
machine says that MagnaRAM is already installed. What
can I do?
A. On Windows 95 systems, remove any lines referring to
MagnaRAM in your System Registry. For example:
1. Click on "Start" and choose the "Run" option.
2. Type in REGEDIT <enter> to load the Registry Editor
program.
3. Click on the Search menu, then click on the Find
option.
4. Type MAGNA <enter>. If you find anything that
refers to MagnaRAM, press <DEL> to remove that
section.
5. Click on Find Next and continue searching until
no more are references found.
On Windows 3.1x / Windows for WorkGroups systems, remove
any lines referring to MagnaRAM located in the SYSTEM.INI
and WIN.INI files. For example:
1. Click on File/Run from the menu of Program Manager.
2. Type in SYSEDIT <enter> to bring up the System
Editor program.
3. Click on Window and select SYSTEM.INI.
4. Locate the line in the [386Enh] section that ends
with MAGNARAM.VXD and remove it.
5. Click on Window and select WIN.INI.
6. Locate the line in the [windows] section that ends
with LOGO31.EXE and remove it.
4. Q. I loaded MagnaRAM and now Windows 3.1x / Windows for
WorkGroups stops responding when I am using it.
A. Below is a list of some things to check about your
Windows configuration:
- Make sure that you are using a PERMANENT Windows swap
file. This can be verified by clicking on the 386Enh
icon in Control Panel, which is by default in the Main
program group. Make sure that you are using the swap
file on an UNCOMPRESSED drive. If you are using disk
compression software such as Stacker or DriveSpace,
use the configuration utilities included with those
applications to increase the size of your uncompressed
drive. Then you can create a permanent swap file on
that drive, and still have room for any other programs
that are needed on the compressed drive. Please
contact the manufacturer of the compression software
you are using or consult the manuals if you are unsure
of how to change the size of your uncompressed drive.
- While you are checking the swap file settings in the
386Enh section of Control Panel, verify that 32-bit
file access is not enabled OR lower the cache size to
1024K or less.
- Using MagnaRAM's setup utility, lower the size of the
compression buffer that MagnaRAM uses, and increase the
threshold setting to 30-40%.
- Edit the SYSTEM.INI file located in the Windows
directory and change the order of the drivers in the
DRIVERS= line. Try moving MAGNARAM.DLL to the beginning
of that line. If that does not resolve the conflict,
try placing MAGNARAM.DLL at the end of the DRIVERS=
line.
5. Q. I installed MagnaRAM on my system and Windows appears to
be running more slowly.
A. MagnaRAM automatically configures itself to your system,
but sometimes it will require fine tuning in order to
work at its peak performance.
For Windows 3.1x or Windows for WorkGroups users, try
going into MagnaRAM's settings section (the screwdriver
icon) and change the PageOverCommit setting from 8 to 3.
This affects the amount of linear (Windows) memory that
is available to your system. Reducing this number will
lower the total amount of linear memory you have
available; however, system performance may increase.
Also, for both Windows 95 and Windows 3.1x / Windows For
Workgroups users, try decreasing the MagnaRAM
Compression Buffer size at an increment of 20-30 percent
until you get an improvement in performance.
6. Q. MagnaRAM does not appear to be doing much. Is it loading?
A. Check to see if MagnaRAM is loading. On Windows 95
systems, use the Registry Editor (REGEDIT) to search for
any lines containing "MAGNA". For Windows 3.1x / Windows
for WorkGroups, edit the SYSTEM.INI and search for the
DRIVERS= line that refers to MagnaRAM. If this entry is
not present, MagnaRAM is not properly installed.
If there are Registry entries containing "MAGNA", check
the MagnaRAM statistics window and make sure that
Compression Buffer Size is set to 10% of the machine's
physical RAM. MagnaRAM's compression techniques may not
take effect immediately, and may not be readily noticed
at Windows startup.
7. Q. MagnaRAM is loaded and working fine, but I no longer get
any sounds in Windows 3.1x / Windows for WorkGroups.
A. After checking that your sound card is setup correctly,
edit the SYSTEM.INI file located in the Windows
directory. Check the DRIVERS= line that references
MagnaRAM. It is possible that when MAGNARAM.DLL was
added to that line during installation, the driver for
the sound card was "bumped off" of the line, especially
if the DRIVERS= line is unusually long. Reinstalling the
driver(s) for the sound card may solve this problem. You
should consult you sound card manual for the necessary
files needed on this line.
8. Q. Why does MagnaRAM fail to load, and why can't I restart
it?
A. You may find that MagnaRAM is is failing to reload some
of its files properly. Uninstall MagnaRAM with its
built-in UnInstall utility, and make sure that the lines
added to the SYSTEM.INI shown on page 30 of the manual
are removed. If not, manually remove them. Then
re-install the program.
9. Q. I am trying to install MagnaRAM, but it will not accept my
serial number nor proceed to the next screen when I
click on the NEXT button.
A. If the NEXT button won't highlight to allow you to go to
the next screen, please verify that the Company Name
field is filled out.
10. Q. MagnaRAM doesn't give me enough memory to run an
application.
A. Sometimes a program requires a certain amount of
physical memory to run. For example, some computer
assisted drawing (CAD) programs require 12 megabytes of
physical memory in addition to any virtual memory they
use. The system may simply need more physical RAM for
such programs. If MagnaRAM does not provide you with
enough LINEAR memory to run a program, try increasing
the size of the permanent Windows swap file. You also
try to decrease the Compression Buffer Size at an
increment of 20-30 percent.
