- MAGNARAM VERSION 2 README FILE FOR WINDOWS 3.1 USERS
-
- This file includes tips to help you get the most out of MagnaRAM. For
- that reason alone, it is worthwhile reading! It also contains
- last-minute information that did not make it into the manual and a few
- corrections to the manual. If you want to print this file for future
- reference, be sure you are in the MagnaRAM directory and type
-
- COPY README.TXT PRN:
-
- at the DOS prompt. Alternatively, you may print this file from the
- Windows Notepad by clicking on File, then Print.
-
- Note also that the online help file included with MagnaRAM is more
- up-to-date than the printed documentation.

- MagnaRAM NEEDS ENHANCED MODE AND VIRTUAL MEMORY
- ================================================
-
- MagnaRAM requires Windows 3.1 to be running in 386 Enhanced Mode, and
- to have Virtual Memory enabled. Virtual memory setup and configuration
- instructions can be found in Chapter 4 of your MagnaRAM user's guide.
-
-
- MagnaRAM AND 'QUICK START' PROGRAMS
- ====================================
-
- Changes to Windows's Virtual Memory settings and MagnaRAM's
- configuration typically require Windows to be restarted for the changes
- to take effect. Programs that allow Windows to be exited and restarted
- quickly may not take such changes into account. Generally, such
- programs should be disabled before you make changes to Windows' Virtual
- Memory settings or MagnaRAM's configuration. After making your
- changes, exit and restart Windows when prompted to do so, either by
- using the Restart dialog box or the standard Windows exit procedures.
- After you have restarted Windows, you may reactivate
-
-
- IF YOUR SYSTEM LOCKS AFTER MagnaRAM IS INSTALLED
- ================================================
-
- In the unlikely event that you experience a system failure after
- you install MagnaRAM, you may wish to consider the following
- possibilities.
-
- The system can become unstable if the Windows swap file is located on
- an area of your hard disk that is being compressed by a disk
- compression program. (This is true even when MagnaRAM is not
- installed.) In general, you should either move your swap file to an
- uncompressed section of your hard disk, or make sure there is plenty of
- free disk space on the compressed drive that contains the swap file.
- The swap file location is set via Windows Control Panel / 386 Enhanced
- / Virtual Memory.
-
- Some programs expect to run in physical RAM, and can cause system
- instability if they do not get the physical memory they expect. You can
- sometimes work around this problem by decreasing the size of disk
- caches, RAM disks, and other TSRs and drivers loaded before you start
- Windows. It may also be possible to work around this problem by
- decreasing the size of MagnaRAM's compression buffer, though MagnaRAM's
- ability to create more Windows memory will decrease along with the size
- of the buffer.
-
- If Windows does not start at all, and you suspect that MagnaRAM may be
- involved, you can disable MagnaRAM temporarily. Use a text editor such
- as DOS' EDIT to edit your WINDOWS\SYSTEM.INI file. Comment out the
- following line in the [386Enh] section by placing a semicolon at the
- front of the line that loads MagnaRAM, which is typically:
-
- device=C:\magnaram\magna31.vxd
-
- Change the line to
-
- ;device=C:\magnaram\magna31.vxd
-
- and Windows will start without loading MagnaRAM. If you are still
- unable to start Windows, it is unlikely in the extreme that MagnaRAM
- has anything to do with the problem. Note that the MagnaRAM control
- panel will refuse to load if MAGNA31.VXD is removed or commented out.
-
- IF YOUR SYSTEM SEEMS TO SLOW DOWN AFTER INSTALLING MagnaRAM
- ===========================================================
-
- If your system seems to slow down after you have installed MangaRAM,
- try decreasing the value of the PAGEOVERCOMMIT statement in MagnaRAM's
- configuration. MagnaRAM generally sets PAGEOVERCOMMIT to a value of 8,
- which is significantly higher than Windows 3.1's default value. It is
- possible that the higher value will create more memory bookkeeping for
- Windows and have an impact on performance. Try a PAGEOVERCOMMIT value
- of 4 (Windows 3.1's default) and see if your system speeds up.
-
- You can also improve performance to a small extent by decreasing the
- size of the MagnaRAM compression buffer, and increasing the minimum
- compression threshold. In both cases, the cost of increased performance
- is less data compression and less extra Windows memory.
-
-
- IF MagnaRAM SEEMS TO HAVE NO EFFECT ON YOUR SYSTEM
- ==================================================
-
- If MagnaRAM is installed and working on your system, you should see the
- MagnaRAM logo, with its expanding RAM chip, as Windows starts up. If you
- don't see this logo, try running the MagnaRAM installation program again.
-
- If MagnaRAM is installed, and the logo appears as you start Windows, check
- the MagnaRAM Configuration screen to make sure that the Disable MagnaRAM
- Memory Compression box is cleared. If this box is selected, MagnaRAM will
- not compress memory on your system.
-
-
- IF APPLICATIONS DO NOT HAVE ENOUGH MEMORY WITH MagnaRAM INSTALLED
- =================================================================
-
- A very large program (for example, a CAD program) might require a huge
- amount of memory before MagnaRAM's data compression even begins. Try
- decreasing the size of the MagnaRAM compression buffer on the MagnaRAM
- Configuration screen, or try increasing the size of your Windows
- virtual memory swap file.
-
-
- ERRATA IN THE PRINTED DOCUMENTATION
- ===================================
-
- As noted above, the correct way to disable MagnaRAM at startup is to
- remove or to comment out the line
-
- device=C:\MagnaRAM\MAGNA31.VXD
-
- in the [386Enh] section of SYSTEM.INI, rather than the line
-
- run=C:\MagnaRAM\LOGO31.EXE
-
- in the [windows] section of the WIN.INI file.
-
- If you wish to disable MagnaRAM permanently, you may do so by following
- this procedure.
-
- 1) Start Windows with MagnaRAM inactive.
-
- 2) When Windows has finished loading, select the MagnaRAM group.
-
- 3) From the menu that is presented on this screen, select MagnaRAM
- Uninstall. This will remove MagnaRAM completely from your hard disk.
- After diagnosing and resolving the conflict, you may then re-install
- MagnaRAM.
-
- The README file first identified on page 3 of the manual is named
- README.TXT (the file you are reading now).
-
- The last paragraph on page 3 notes that MagnaRAM will appear under the
- Start menu in Windows 95, under the name MagnaRAM 2 in the Programs
- sub-menu. The correct name is MagnaRAM. All subsequent occurrences of
- "MagnaRAM 2" should read "MagnaRAM" instead.
-
- On page 4, in the section "To uninstall MagnaRAM", the first step
- suggests that you double-click on the MagnaRAM Uninstall item. A
- single click is all that is required. Subsequent references to
- double-clicking at any point in the Start menu or its submenus should
- refer to a single click instead.
-
- On page 9, the acronym "RMA" should read "RAM" instead.
-
- The last paragraph on page 17 of the manual, which continues on page
- 18, contains incorrect information and should be ignored.
-
- The last paragraph on page 18 is similarly incorrect and should be
- ignored. MagnaRAM's installation does create a backup version of
- WIN.INI and SYSTEM.INI, and places them in the directory into which you
- installed MagnaRAM.
-
- The information on page 21, which notes the changes that MagnaRAM makes
- to your system configuration, is incorrect. MagnaRAM does not use a
- .DLL for any of its services, but instead relies on a Windows Virtual
- Device Driver (VxD). The name of this VxD, and the method by which it
- is loaded, depends on your version of Windows. In Windows 3.1,
- MagnaRAM is loaded by a line in the [386Enh] section of the Windows
- SYSTEM.INI file:
-
- device=c:\magnaram\magna31.vxd
-
- In Windows 95, MagnaRAM's VxD is loaded via the Windows Registry,
- under the HKEY_LOCAL_MACHINE entry in the path
-
- \System\CurrentControlSet\Services\VxD\Quarterdeck_MagnaRAM
-
- The Display_Compression parameter, described on page 22, is no longer a
- MagnaRAM parameter.
-
- 4K sections of memory, as referred to on page 26 are "pages", rather
- than "+pages".
