- QEMM and DoubleDisk Gold 6.0
-
-
- This QEMM 7 technote is available through our standard support
- channels under the following filenames:
-
- Quarterdeck Technical Support BBS: DBLDISK.TEC
- CompuServe: DBLDSK.TEC
- Q/FAX: #218
-
-
- Subject: Running Optimize with DoubleDisk Gold version 6.0.
-
-
- 1. This troubleshooting guide is designed to help the individual
- who has QEMM and DoubleDisk Gold version 6.0 installed on his or
- her machine and has run (or wants to run) Optimize.
-
- 2. To avoid confusion, we will refer to COMPRESSED and
- UNCOMPRESSED drives whenever possible. The COMPRESSED drive will
- always be the one that DoubleDisk creates to hold most of your
- programs and data. The UNCOMPRESSED drive will be the smaller
- BOOT drive.
-
- 3. The information below is relevant if the following
- assumptions are true:
-
- A. You have DoubleDisk Gold v6.0 and are SWITCHING drive names.
- B. You had a ONE partition drive before DoubleDisk was installed.
- C. Your DoubleDisk (COMPRESSED) drive is C: (AFTER bootup)
- D. Your BOOT (UNCOMPRESSED) drive is D: (AFTER bootup)
-
- The best way to determine which drive is which is to type VOL and
- <ENTER> at the DOS prompt. If DoubleDisk is switching drive
- names and you had only one partition before installing the
- program, most likely the C: drive is the actual COMPRESSED drive.
- If you type VOL C: you should see the following:
-
- Volume in drive C is DUBLDISK-C0
-
- 4. Before you can run Optimize with DoubleDisk you will have to
- stop DoubleDisk from switching drive names. This means that you
- need to make the UNCOMPRESSED drive the C: drive. Directions are
- given later in the technote.
-
- THE FOLLOWING INSTRUCTIONS WILL TAKE YOU STEP BY STEP THROUGH
- OPTIMIZING WITH DOUBLEDISK GOLD ON YOUR SYSTEM. TO BE SUCCESSFUL,
- YOU MUST FOLLOW THE INSTRUCTIONS ONE STEP AT A TIME.
-
- BEFORE FOLLOWING THE TROUBLESHOOTING INSTRUCTIONS BELOW,
- PLEASE FOLLOW THESE SIMPLE STEPS TO CREATE
- A BOOTABLE FLOPPY DISKETTE
-
- To create a bootable floppy, format a floppy disk with the DOS
- system on it. (If you are not familiar with the process of
- creating a boot disk, please refer to your DOS manual.) Next,
- copy the following files to it: COMMAND.COM, QEMM386.SYS,
- DUBLDISK.SYS, ACTIVATE.EXE, DRVOFF.EXE, CONFIG.SYS, AND
- AUTOEXEC.BAT.
-
- DUBLDISK.SYS, ACTIVATE.EXE, and DRVOFF.EXE can be found in the
- \DUBLDISK directory.
-
- This will allow you to boot up your DoubleDisk system if you ever
- lose your CONFIG.SYS and AUTOEXEC.BAT files on the hard disk.
-
- OPTIMIZE WITH QEMM AND DOUBLEDISK GOLD
-
- If DoubleDisk is performing a switch of drive names, a bit of
- preparation must first be completed before running QEMM's
- Optimize program. Unless this preparation is done correctly,
- Optimize will not complete successfully.
-
- If you have NOT already attempted to run Optimize, you may skip
- to Step # 5.
-
- 1. If you have already attempted to run Optimize, most likely
- you no longer have access to your COMPRESSED DoubleDisk drive.
- Even though your machine boots up to a C: prompt, if you look at
- the contents of the drive it will appear that you only have a
- small number of your files resident. Also, it will appear that
- the total capacity of your hard drive is only about 2 megabytes.
- THIS IS NOTHING TO BE CONCERNED ABOUT.
-
- 2. On the C: drive, simply type the following:
-
- COPY C:\CONFIG.DBL CONFIG.SYS <ENTER>
- COPY C:\AUTOEXEC.DBL AUTOEXEC.BAT <ENTER>
-
- 3. After completing the above, reboot your computer. At some
- point during the boot process, you will see the following:
-
- C:\> C:\DUBLDISK\ACTIVATE.EXE A C0=D , S C:=D
- File: C:\DUBLDISK.000 Activated as disk D:
- Drive letters C: and D: have been interchanged.
- DoubleDisk has detected changes in the following files:
- * CONFIG.SYS
- * AUTOEXEC.BAT
- Would you like to update the file(s)? (Y)es/(N)o
-
- MAKE SURE THAT YOU SELECT "N" FOR NO.
-
- 4. Once you get back to the C: prompt, the first thing you will
- want to do is make sure that the CONFIG.SYS and AUTOEXEC.BAT
- files are the same on both the COMPRESSED and UNCOMPRESSED
- drives. The C: drive at this point should be your COMPRESSED
- drive. To determine this, just type: VOL <ENTER> at the C:
- prompt. You should see the following: "Volume in drive C: is
- DUBLDISK-C0" or something close to it.
-
- Look at the CONFIG.SYS and AUTOEXEC.BAT files on the D: drive.
- These should be the GOOD ones. The two files should look like
- they did before you ran Optimize. In contrast, if you looked at
- the AUTOEXEC.BAT file on the C: drive, it should have only a
- single line in it that reads: "@C:\QEMM\OPT2.BAT." If this is
- the case, just copy the CONFIG.SYS and AUTOEXEC.BAT files from D:
- to C: by typing:
-
- COPY D:\CONFIG.SYS C:\CONFIG.SYS <ENTER>
- COPY D:\AUTOEXEC.BAT C:\AUTOEXEC.BAT <ENTER>
-
- Reboot your computer. You should now be back to a normal system.
-
- IF YOU HAVE NOT YET RUN OPTIMIZE, PLEASE FOLLOW THE DIRECTIONS
- BELOW.
-
- 5. The next thing you need to do is make sure that QEMM is
- installed on both the UNCOMPRESSED and COMPRESSED drives. If you
- had installed DoubleDisk AFTER installing QEMM, DoubleDisk will
- create a QEMM directory on both drives and copy some files over.
-
- If you installed DoubleDisk BEFORE installing QEMM you will need
- to create a QEMM directory on the D: drive after installing on
- C:. After creating the directory on D:, simply copy the QEMM
- files from C:\QEMM to D:\QEMM. If you do not have room to copy
- over every QEMM file from C:, below is a list of the most
- important files.
-
- 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. In order to run Optimize with DoubleDisk, you must disable
- DoubleDisk's drive SWITCHING which is done from the AUTOEXEC.BAT
- file. When DoubleDisk is installed on your system it puts the
- following line as the FIRST line in your AUTOEXEC.BAT file:
-
- C:\DUBLDISK\ACTIVATE.EXE A C0=D ,S C:=D
-
- The parameter that performs the drive SWITCHING function is at
- the end of the line: ",S C:=D."
-
- 7. To set up your system so that you may run Optimize, you will
- only need to edit your AUTOEXEC.BAT file, not your CONFIG.SYS
- file. Below is a sample AUTOEXEC.BAT file with DoubleDisk
- installed.
-
- C:\DUBLDISK\ACTIVATE.EXE A C0=D , S C:=D
- D:\DUBLDISK\DRVOFF.EXE
- PROMPT=$P$G
- PATH=D:\DUBLDISK;C:\DOS;C:\QEMM
-
- ** IMPORTANT **
- It is important that you follow the instructions below,
- to the letter, in order to insure success.
-
- 8. Remove the ", S C:=D" parameter from the first line so that
- it now reads:
-
- C:\DUBLDISK\ACTIVATE.EXE A C0=D
-
- 9. Reverse ALL drive designations from the first line down. Do
- NOT reverse drive designations in the FIRST line. The
- AUTOEXEC.BAT file should now look like this:
-
- C:\DUBLDISK\ACTIVATE.EXE A C0=D
- C:\DUBLDISK\DRVOFF.EXE
- PROMPT=$P$G
- PATH=C:\DUBLDISK;D:\DOS;D:\QEMM
-
- Notice the difference between the two samples above. We have
- changed ALL C: entries to D: and vice versa.
-
- 10. Now, copy the AUTOEXEC.BAT file to D: and then reboot the
- machine. Once the reboot is complete, you should no longer be
- switching drives. This means that your C: drive is your
- UNCOMPRESSED drive and this is the drive from which QEMM boots.
- Just to make sure, type VOL D: <ENTER>. This should reveal the
- D: drive as DUBLDISK-C0. If this is not the case, check your
- AUTOEXEC.BAT file and make sure you have removed the SWITCHING
- parameter above.
-
- 11. Run Optimize. Once Optimize is complete, edit the
- AUTOEXEC.BAT file and reverse your earlier procedures. That is,
- put back the SWITCHING parameter ", S C:=D" and reverse the drive
- designations below the FIRST line. If you decide that you no
- longer want to SWITCH drive names upon bootup, you do not have to
- do anything. Just keep in mind that most of your programs will
- be on the D: drive.
-
- 12. You are done! You have successfully run OPTIMIZE with
- DoubleDisk.
