THE QEMM-386/SUPERSTOR TROUBLESHOOTING GUIDE
This troubleshooting guide is designed to help the individual who has QEMM-386
(or QEMM-50/60 or QRAM) and SuperStor 2.04 or SuperStor Pro installed on his
or her machine and has run, or wants to run, OPTIMIZE. If you have not yet
run OPTIMIZE, please read the General Information section below, then proceed
to either Section 1 or Section 2 depending on if you installed QEMM-386 BEFORE
or AFTER installing SuperStor.
Throughout this document we will refer to QEMM-386. With the exception of
QEMM-386's Stealth feature the same solutions presented for QEMM-386 will also
apply to users of QEMM-50/60 or QRAM. The OPTIMIZE program is the same for
all three products. Note that the STEALTH option exists only with QEMM- 386.
1. To avoid confusion we will refer to COMPRESSED and UNCOMPRESSED drives
whenever possible. The COMPRESSED drive, which is actually a very large
hidden file with a drive ID, will always be the one that SuperStor creates to
hold most of your programs and data.
2. Since you cannot boot from the COMPRESSED drive, SuperStor sets aside a
small portion of the UNCOMPRESSED drive to boot from. Depending upon which
version of SuperStor you have, this partition may or may not be easily
3. Your UNCOMPRESSED drive is always drive C: before bootup. When the
SuperStor driver (SSTORDRV.SYS) executes during bootup it then allows access
to the large COMPRESSED partition and gives it the next available drive ID,
usually D: This partition is really a very large hidden file called
SSPARTSS.ADD (if you have access to both the COMPRESSED and UNCOMPRESSED
drives, the file will be called SSPARTSS.SWP).
4. After the SuperStor driver executes, another driver (DEVSWAP.COM) usually
follows it. When this driver executes, it swaps drive names so that the
COMPRESSED partition becomes C: and the UNCOMPRESSED partition becomes D:.
Basically, it is just reversing the drive names so that your applications will
still think that they are on drive C:
5. If you have allowed SuperStor to compress the entire hard drive, you will
not be able to access the UNCOMPRESSED partition after boot, unless you run a
utility called ADD2SWP.EXE, found on your SuperStor program diskette. From
the diskette, just type : ADD2SWP C:
access to both your COMPRESSED and UNCOMPRESSED drives.
6. If you have configured SuperStor to reserve space on the UNCOMPRESSED
drive to be accessed by a different drive ID you will already be able to
access the UNCOMPRESSED partition easily. You are given the option to reserve
this space when you are running the SSTOR program to create your COMPRESSED
drive(s). In version 2.04 the default is NO. If you press ENTER when
encountering this option SSTOR will set-up SuperStor to compress your whole
7. If you have not yet installed SuperStor 2.04, Quarterdeck recommends that
you select YES to override the default. Beginning with SuperStor Pro version
1.0, the default is YES. You only have to press ENTER at this prompt. When
the program then asks you for a size to make the UNCOMPRESSED drive enter 2048
to add two megabytes to that drive size.
8. To determine which drive is COMPRESSED or UNCOMPRESSED start the SSTOR.EXE
program in the C:\ADDSTOR directory. Under the heading "System Device List"
will be information pertaining to all drives on your computer.
9. If before you installed SuperStor your hard disk drive had more than one
partition, i.e., a C: and D: partition, SSTORDRV.SYS will select the next
available drive name for its container file. If you had a C: and D: partition
and you COMPRESSED the C: drive only then your drives will be set up as
follows when SuperStor is installed:
C: becomes E:
D: is still D: unless you compress that as well. If you do compress
D:, it becomes F:
The troubleshooting guide below is based on a one partition drive. If your
drive has multiple partitions then you must determine what drive C: swaps to
and use the appropriate drive name.
10. If you are using a disk caching program with SuperStor, be very careful
to determine whether it is compatible with SuperStor or not. For instance
Microsoft Windows' 3.1 SMARTDRV.EXE will lock up your system upon bootup, if
you load the SSTORDRV.SYS driver into High Ram with LOADHI.SYS. At the time
of this writing, Norton NCACHE version 6, will not work under any
circumstances with SuperStor installed on your machine.
BE ABSOLUTELY CERTAIN THAT YOU READ THE README.TXT FILE IN YOUR ADDSTOR
DIRECTORY FOR ANY POTENTIAL CONFLICTS WITH OTHER PROGRAMS AND DRIVERS.
11. You should always have a bootable floppy diskette available which will
execute SuperStor and give you access to your COMPRESSED drive. To create
this format a floppy diskette with the /S parameter so that it becomes a boot
When this disk has been formatted copy the following files from the C: drive
to the floppy diskette: SSTORDRV.SYS, DEVSWAP.COM, CONFIG.SYS, AUTOEXEC.BAT.
Once those files have been copied over check the contents of them. The
CONFIG.SYS file should contain at least the following lines:
DEVICE=\SSTORDRV.SYS /NOHIGH (SuperStor Pro requires /NOUMB instead)
12. If you want QEMM-386's LOADHI.SYS driver to load SuperStor version 2.04
into High RAM you must place the "/NOHIGH" parameter at the end of the
SuperStor device line. If you are using SuperStor Pro you must use the
"/NOUMB" parameter instead of "/NOHIGH." SuperStor does not automatically
place either of the parameters on the line. The line should read as follows:
DEVICE=\SSTORDRV.SYS /NOHIGH (SuperStor 2.04)
DEVICE=\SSTORDRV.SYS /NOUMB (SuperStor Pro)
The AUTOEXEC.BAT file should contain at least the following lines:
These files on the boot floppy will allow you to access your SuperStor
COMPRESSED drive and navigate the hard drive.
SUPERSTOR INSTALLED FIRST
If SuperStor is already installed on your hard drive and you now install QEMM-
386 and run OPTIMIZE then you must follow the section below.
1. If you install QEMM-386 and run OPTIMIZE on a system with SuperStor
already installed, SuperStor will fail to execute during the first reboot of
the OPTIMIZE program. This is because OPTIMIZE places device statements on
the SSTORDRV.SYS line, but the files necessary to complete the boot cannot be
found on the UNCOMPRESSED boot drive.
2. Since SuperStor fails to load, you will only have access to your UNCOMPRESSED
drive after bootup. It is an easy process to correct this situation. All you
have to do is create a new, temporary, CONFIG.SYS file on the UNCOMPRESSED
drive, now drive C:, and then reboot. To do this first rename the old
CONFIG.SYS file by typing:
RENAME CONFIG.SYS CONFIG.XXX
Now, create a new CONFIG.SYS file by typing the following:
COPY CON CONFIG.SYS
The cursor will now be below the "C" in COPY. Now, type:
NOTE: IF YOU HAVE ANY OTHER DRIVERS, SUCH AS A DISK PARTITIONER, THAT ARE
ESSENTIAL TO BOOT YOUR MACHINE INCLUDE THOSE IN THE TEMPORARY CONFIG.SYS
FILE. IF YOU DO NEED TO BOOT WITH A DISK PARTITIONER MAKE SURE IT LOADS
BEFORE SSTORDRV.SYS. DON'T WORRY ABOUT ANY OTHER DRIVERS YOU MAY HAVE HAD IN
THE ORIGINAL CONFIG.SYS FILE: ONCE YOU HAVE HAVE REBOOTED THE MACHINE YOUR
ORIGINAL CONFIG.SYS FILE WILL BE INTACT.
Now, press the F6 key and
ONE FILE COPIED
3. Reboot the machine.
4. Because of SuperStor program designs the untouched CONFIG.SYS file on the
COMPRESSED drive will automatically overwrite the temporary CONFIG.SYS file on
the UNCOMPRESSED drive. The contents of both CONFIG.SYS files will then be
the same as before you installed QEMM-386 and ran OPTIMIZE.
FULL DISK COMPRESSION
IF YOU INSTALLED SUPERSTOR TO COMPRESS YOUR WHOLE HARD DRIVE, PROCEED TO
STEP 2 IN "OPTIMIZING WITH QEMM-386 AND SUPERSTOR."
PARTIAL DISK COMPRESSION
IF YOU INSTALLED SUPERSTOR TO COMPRESS ONLY A PORTION OF YOUR HARD
DISK DRIVE, PROCEED TO STEP 2 IN "OPTIMIZING WITH QEMM-386 AND SUPERSTOR."
ONCE YOU HAVE COMPLETED STEP 2, PROCEED TO EITHER STEP 4 OR 6, DEPENDING
UPON WHETHER OR NOT YOU HAVE LEFT ADEQUATE ROOM ON YOUR UNCOMPRESSED
PARTITION TO HOLD ALL QEMM-386 AND DOS FILES.
QEMM-386 INSTALLED FIRST
If QEMM-386 is currently installed on your hard disk drive and you now install
SuperStor, you then need to follow the instructions in the section below.
IMPORTANT NOTE: As of SuperStor Pro 1.0, Addstor recommends that if you have a
memory resident program, such as a memory manager, installed and running, you
must disable the memory resident program BEFORE installing SuperStor. At
Quarterdeck, we have installed SuperStor Pro successfully with QEMM-386
running. If you choose to follow their advice, disable QEMM-386, and your
memory resident programs, by placing a REM statement at the beginning of the
line that loads such a program.
1. After you install SuperStor you then have to run SSTOR.EXE to do the
actual compression of your hard drive. The default of SuperStor 2.04 is to
compress all of the hard drive space. As of SuperStor Pro 1.0, the default is
to leave a portion (the size is specified by the user) of the hard drive
uncompressed. No matter which version you are using, you should make sure you
leave at least a 2 MB portion uncompressed.
2. If you accept the default of SuperStor 2.04 to compress the whole hard
disk drive or if you override the default of SuperStor Pro, SuperStor leaves a
tiny boot partition with only COMMAND.COM and other system files, as well as
the SuperStor drivers resident. If QEMM-386 is installed when you install
SuperStor, the QEMM386.SYS device driver will be placed into the root
directory of the boot drive.
Also, the QEMM-386 line in the CONFIG.SYS will be changed from:
DEVICE=C:\QEMM\QEMM386.SYS RAM to DEVICE=C:\QEMM386.SYS RAM
3. Upon installation, SuperStor does not create a QEMM directory on the
UNCOMPRESSED drive, nor does it copy over the pertinent QEMM-386 files from
the COMPRESSED drive.
4. If you have accepted the default of compressing the whole drive, the drive
letter D: is not readily accessible. How to access the UNCOMPRESSED drive
will be explained in detail later in this troubleshooting guide. If you have
only compressed a portion of the hard disk drive you already have access to
the UNCOMPRESSED portion of the drive.
5. The net result of the above is that after installing SuperStor,
compressing the hard disk, and rebooting the machine, QEMM-386 will execute,
but any lines in the CONFIG.SYS that precede SSTORDRV.SYS and that have
LOADHI.SYS statements will fail. After following the instructions below in
"Optimizing with QEMM-386 and SuperStor" those files will then be in the
correct directory for OPTIMIZE to perform.
FULL DISK COMPRESSION
IF YOU INSTALLED SUPERSTOR TO COMPRESS YOUR WHOLE HARD DISK DRIVE PROCEED
TO STEP 1 IN "OPTIMIZING WITH QEMM-386 AND SUPERSTOR."
PARTIAL DISK COMPRESSION
IF YOU HAVE INSTALLED SUPERSTOR TO COMPRESS ONLY A PORTION OF YOUR
HARD DISK DRIVE PROCEED TO STEP 1 IN "OPTIMIZING WITH QEMM-386 AND
ONCE YOU HAVE COMPLETED STEP 2 PROCEED TO EITHER STEP 4 OR 6, DEPENDING
UPON WHETHER OR NOT YOU HAVE LEFT ADEQUATE ROOM ON YOUR UNCOMPRESSED
PARTITION TO HOLD ALL QEMM-386 AND DOS FILES.
OPTIMIZING WITH QEMM-386 AND SUPERSTOR
BEFORE FOLLOWING THE STEPS BELOW MAKE CERTAIN THAT YOU HAVE READ ALL THE
INFORMATION ABOVE PERTAINING TO THE ORDER AND METHOD USED TO INSTALL QEMM-386
AND SUPERSTOR ON YOUR COMPUTER. ALSO MAKE SURE ANY IMPORTANT FILES HAVE BEEN
BACKED UP. THIS INCLUDES BOTH THE CONFIG.SYS AND AUTOEXEC.BAT FILES AND ANY
OTHER FILES YOU FEEL ARE IRREPLACEABLE.
* IF YOU HAVE CONFIGURED SUPERSTOR TO COMPRESS YOUR WHOLE HARD DISK DRIVE,
PLEASE FOLLOW THE STEPS BELOW FROM 1 TO 16. IF YOU INSTALLED QEMM-386 AFTER
INSTALLING SUPERSTOR YOU MAY SKIP STEP 1.
* IF YOU HAVE CONFIGURED SUPERSTOR TO COMPRESS ONLY A PORTION OF YOUR HARD
DISK DRIVE BUT DID NOT LEAVE ENOUGH ROOM ON THE UNCOMPRESSED PORTION TO COPY
ALL QEMM-386 AND DOS FILES TO THAT PORTION, PLEASE FOLLOW THE STEPS BELOW
FROM 4 TO 16.
1. On the C: COMPRESSED drive, edit the QEMM-386 device line in the
CONFIG.SYS file to read:
Save the CONFIG.SYS file.
2. Place the SuperStor program diskette into drive A:. Log onto drive A:
The program will then report:
ADD2SWP has completed, your PC needs to be rebooted.
Press the [ENTER] key to reboot the PC
3. Remove the diskette and press ENTER. After the computer completes
its reboot you will then have access to both your COMPRESSED and
4. Start SSUTIL.EXE by typing: SSUTIL
at the C: prompt, and run SHRINK DISK from within that program.
Select an amount to shrink the COMPRESSED disk by. Quarterdeck
recommends a minimum of 1024 Kb with 2048 Kb preferred.
5. EXIT and REBOOT.
THE NEXT STEPS CAN BE FOLLOWED IF YOU HAVE CONFIGURED SUPERSTOR TO COMPRESS
ONLY A PORTION OF YOUR HARD DISK DRIVE AND LEFT ENOUGH ROOM FOR ALL QEMM-386
AND DOS FILES OR IF YOU HAVE JUST FOLLOWED STEPS 1-4.
6. Log onto drive D: the UNCOMPRESSED drive. Create a QEMM
directory by typing the following:
7. Copy all QEMM-386 files from the COMPRESSED drive into the QEMM
directory on the UNCOMPRESSED drive.
8. While still on the UNCOMPRESSED drive D: create directories pertaining to
all other drivers loading from the CONFIG.SYS file. For example, if
you have a couple of lines in your CONFIG.SYS file that read:
then create a MOUSE directory and a DOS directory on the
UNCOMPRESSED drive. Then, copy the MOUSE.SYS and ANSI.SYS drivers
from the CONPRESSED drive to their respective directories on the
Do the same for all other drivers loading from the CONFIG.SYS file.
9. Log back on to drive C:, the COMPRESSED drive. Edit the CONFIG.SYS
file in the following ways:
A. Move the two SuperStor device lines to the bottom of the
B. If you haven't already done so, place a blank space and the
"/NOHIGH" parameter (for SuperStor 2.04 only) or the "/NOUMB"
parameter (for SuperStor Pro only) at the end of the
SSTORDRV.SYS device line.
C. Place a REM and a blank space in front of the line that reads:
DEVICE=\DEVSWAP.COM so it now reads: REM DEVICE=\DEVSWAP.COM.
Save the CONFIG.SYS file but do NOT reboot yet.
IMPORTANT NOTE: YOU MUST PLACE THE "/NOHIGH" PARAMETER (for SuperStor 2.04)
OR THE "/NOUMB" PARAMETER (for SuperStor Pro) AT THE END OF THE \SSTORDRV.SYS
DEVICE LINE TO ALLOW OPTIMIZE TO SUCCESSFULLY LOAD THE DRIVER INTO HIGH RAM.
THE SIZE OF THE DRIVER, SSTORDRV.SYS, CAN VARY WHEN IT IS LOADED INTO HIGH
RAM. THE LARGEST SIZE WE HAVE SEEN AT QUARTERDECK IS 71K.
10. Still on the COMPRESSED C: drive, edit the AUTOEXEC.BAT file and
reverse all drive designations from C: to D: or D: to C:. For
example if a line reads:
change it to read:
Make sure you also reverse the drive designations in your path
If you are using the CALL command to CALL batch files from the
AUTOEXEC.BAT file, make sure that the drive designations in the
CALLed batch file are also reversed. For instance, if you have a
line in your AUTOEXEC.BAT file that reads:
and logs you onto a network make sure you reverse the drive
designations in both the above line and in the batch file
11. Save the AUTOEXEC.BAT file and copy to the D:\ drive.
12. Reboot the computer.
13. Run OPTIMIZE.
14. After OPTIMIZE is complete edit the CONFIG.SYS file on the
UNCOMPRESSED drive and remove the REM and blank space in front of
the DEVSWAP.COM device line. It's very important that you edit the
CONFIG.SYS file on the UNCOMPRESSED drive which will be C:. After
editing save the file and copy it to the COMPRESSED D: drive by
COPY C:\CONFIG.SYS D:\
15. Edit the AUTOEXEC.BAT file on the UNCOMPRESSED C: drive and once
again reverse the drive designations. Be very careful that you
find ALL drive designations. Some lines may have more than one
drive designation in the same command so watch out for that.
After editing the AUTOEXEC.BAT file on the UNCOMPRESSED C: drive
save and copy it to the COMPRESSED drive D:.
16. The OPTIMIZE process is now complete. Reboot the computer which
will once again swap your drive names and your work is done.
