- QEMM AND SUPERSTOR DISK COMPRESSION
-
-
- This QEMM 7 technote is an abridged version of a technical
- bulletin that is available through our standard support channels.
- The information contained in this version pertains ONLY to QEMM
- version 7.0. If you need information relating to earlier versions
- of QEMM you can obtain the unabridged version from the following
- sources:
-
- Quarterdeck Technical Support BBS: SSTOR.TEC
- CompuServe: SSTOR.ZIP
- Q/FAX: #249

-
- Subject: Notes on using AddStor's SuperStor disk compression
- utility package with Quarterdeck Expanded Memory Manager.
-
- PLEASE NOTE: The information contained in this technical
- bulletin pertains ONLY to QEMM version 7.0. If you require
- information relating to earlier versions of QEMM, you should
- obtain the longer, unabridged version of this technote which is
- available through our standard support channels under the same
- filename. See CONTACT.TEC (located in your QEMM\TECHNOTE
- directory) for information on obtaining technical bulletins.
-
-
- QEMM's Optimize program is fully compatible with SuperStor 2.0,
- 2.04 and SuperStor Pro. However, a few steps may have to be
- followed before running Optimize.
-
- 1. In order for QEMM's LOADHI.SYS to load the entire device
- driver into upper memory, you must place a /NOUMB parameter
- at the end of the SSTORDRV.SYS device line in your CONFIG.SYS
- file.
-
- 2. When SSTORDRV.SYS (the SuperStor device driver) is loaded into
- upper memory, it usually takes about 75K. If loaded into
- conventional memory, it usually takes about 41K. This is an
- inherent limitation of SSTORDRV.SYS and is NOT a QEMM issue.
-
- 3. When QEMM is installed on a system on which SuperStor is
- already installed, it creates a QEMM directory on the
- UNCOMPRESSED boot drive and copies pertinent QEMM files to
- that drive. If you do not have enough room on your
- uncompressed drive to hold the necessary files, the
- installation will terminate.
-
- To rectify this, you must run Addstor's utility program SSUTIL
- and shrink the size of the COMPRESSED disk. To be on the safe
- side, shrink it by a minimum of 2048K. Although QEMM will
- only use a portion of that disk space, you should have
- sufficient space left over for new device drivers, temporary
- files, or other files or programs you may need to store on the
- UNCOMPRESSED drive. Refer to your SuperStor manual for
- information on using SSUTIL.
-
- 4. If you install SuperStor on a system that already has QEMM
- installed on it, the SuperStor installation program will
- change the QEMM device statement from:
-
- DEVICE=C:\QEMM\QEMM386.SYS RAM
-
- to
-
- DEVICE=C:\QEMM386.SYS RAM
-
- You MUST edit the line to once again read:
-
- DEVICE=C:\QEMM\QEMM386.SYS RAM
-
- If you like, you can use the editor in QEMM's QSETUP program
- or in Manifest.
-
- 5. If you install SuperStor after installing QEMM, you must
- manually create a QEMM directory on the UNCOMPRESSED drive and
- copy pertinent QEMM files from the COMPRESSED drive to the
- UNCOMPRESSED drive. The necessary files are:
-
- QEMM386.SYS
- TESTBIOS.COM
- OPTIMIZE.COM
- RSTRCFG.SYS
- LOADHI.COM
- LOADHI.SYS
- MCA.ADL [if a Micro Channel machine]
- WINHIRAM.VXD
- WINSTLTH.VXD
- MFT.EXE
- QDPMI.SYS [if loaded in CONFIG.SYS]
- DOSDATA.SYS [if using DOS-UP]
- DOS-UP.SYS [if using DOS-UP]
- QSETUP.EXE [if you have room for it]
-
- 6. If you enabled QEMM's DOS-UP feature prior to installing
- SuperStor, the SuperStor installation will move the two
- DOS-Up device lines to the wrong place in the CONFIG.SYS file.
- The SuperStor installation program moves the QEMM386.SYS
- device line to the top of the CONFIG.SYS file, then loads the
- two SuperStor drivers, SSTORDRV.SYS and DEVSWAP.COM, followed
- by DOSDATA.SYS and DOS-UP.SYS. THIS IS WRONG.
-
- You MUST edit your CONFIG.SYS file so that the SuperStor
- drivers do NOT load until after the three QEMM drivers.
- You may also be loading QEMM's QDPMI.SYS device driver in your
- CONFIG.SYS file, but the order in which this driver loads is
- not important.
-
- The QEMM drivers MUST load as follows:
-
- DEVICE=C:\QEMM\DOSDATA.SYS
- DEVICE=C:\QEMM\QEMM386.SYS RAM [any additional parameters]
- DEVICE=C:\QEMM\DOS-UP.SYS
-
- with the SuperStor drivers loaded AFTER these three lines.
-
- 7. In order to prevent confusion when running QSetup, you MUST
- delete the QEMM386.SYS driver from the ROOT directory of both
- the COMPRESSED and UNCOMPRESSED drives.
-
- PLEASE NOTE: You MUST NOT delete the QEMM386.SYS drivers from
- your QEMM directories.
-
- 8. Once you have performed the above steps, you should have no
- problem running either Optimize or QSetup with SuperStor.
