If Backup, Undelete, and/or Anti-Virus were not on your system when you installed MS-DOS 6.2 Step-Up, but you now want the MS-DOS 6.2 versions of these programs and you are using Stacker version 3.11, the procedure in the MS-DOS 6.2 Step-Up README.NOW file for installing them does not work correctly. To work around this situation, follow the steps below.
To work around this problem:
- Use the MS-DOS Expand utility (EXPAND.EXE) to expand the required files (using the table below for reference) from the original MS-DOS 6 Upgrade disk.
NOTE: If you expanded the Backup or Anti-Virus files in step 1, skip to step 4. If you expanded the MS-DOS-based or Windows-based version of Undelete, go to step 2.
- Run 62STAC.EXE, or run Debug as described below in the section titled "Changing the Stacker Version Number in Memory" to change the Stacker version number from 3.11 to 3.10 in memory.
- Run MS-DOS 6.2 Step-Up to update the files.
- Manually create the MSTOOLS group and icons in Microsoft Windows if you expanded the Windows-based versions of Backup, Anti-Virus, and/or Undelete.

Changing the Stacker Version Number in Memory
To change the Stacker version number in memory (so you can run MS-DOS 6.2 Step-Up), contact STAC Electronics to obtain the 62STAC.EXE file, or follow the procedure below. You can order the 62STAC.EXE file from STAC Electronics, or you can download it from the STAC Electronics bulletin board service at (619) 431-7405.
If you do not obtain 62STAC.EXE, you can work around this problem by using the Debug program to make the Stacker driver report version 3.1 instead of 3.11. The following procedure uses Debug to change the memory location that Setup looks at to determine the Stacker version.
- If you have not already done so, exit SETUP by pressing F3. If necessary, boot from the Uninstall Disk 1 and follow the instructions on the screen to return to your previous version of MS-DOS.
- At the MS-DOS command prompt, type the following command and press ENTER:
mem /c /p
- Check the name column for the STACKER or STACHIGH program.
- Using the program name found in the previous step, type the appropriate command below and then press ENTER:
- At the MS-DOS command prompt, enter the following command and press ENTER:
- At the Debug prompt, type the following command and press ENTER
s <ssss>:0000 ffff 5a a5
where <ssss> is the last four digits of the segment address displayed in step 4. For example, if the segment address from step 4 was 0025F, type:
s 025f:0000 ffff 5a a5
Type the following command at the Debug prompt and then press ENTER
where <ssss:oooo> is the segment:offset displayed by step 6. For example:
Debug displays a block of information similar to the following:
025F:0A40 5A A5 37 01 D0 00 025F:0A50 08 01 14 01 03 02 76 10-00 00 03 00 A4 09 20 6D 025F:0A60 00 00 00 00 00 00 00 00-00 0A 00 00 00 0A 00 00 025F:0A70 20 63 00 00 00 02 00 40-E0 69 3A 00 CD 13 CD 14 025F:0A80 CD 01 CD 03 1A 00 02 03-00 00 81 07 03 01 14 00 025F:0A90 CA 00 00 80 5E 19 00 00-00 00 00 00 53 57 41 50 025F:0AA0 00 01 02 03 04 05 06 07-08 03 0A 0B 0C 0D 0E 0F 025F:0AB0 10 11 12 13 14 15 16 17-18 19 00 00 B0 03 F9 01 025F:0AC0 00 00 00 00 00 00 24 01-01 01
Looking across the top row of this block, you should see the "5A A5 37 01" pattern. If you see this pattern, proceed to step 8.
If you do not see this exact pattern and more than one segment:offset pair was displayed by step 6, repeat step 7 for each segment:offset pair until you locate the memory block that contains this pattern.
If you do not see this exact pattern and you have checked all segment:offset pairs displayed by step 6, exit Debug by pressing Q and ENTER. Contact STAC Electronics to obtain the 62STAC.EXE file.
- After locating the pattern as described in step 7, type the following command at the Debug prompt and press ENTER
where <ssss:oooo> is the segment:offset pair used in step 7. For example:
In this example, Debug displays the following (the segment:offset varies):
- Press the SPACEBAR two times. Debug displays the following:
025F:0A4A 5A. A5. 37.
- Type 36 and press ENTER. This returns you to the Debug hyphen prompt.
- Press Q and ENTER to quit Debug.
DO NOT restart your computer. If you do, you must go through this procedure again.
- Run the MS-DOS 6.2 Setup program.
At the time MS-DOS 6.2 was released, the current version of Stacker was 3.1. Microsoft ensured MS-DOS 6.2 Upgrade and MS-DOS 6.2 Step-Up can detect and install correctly over Stacker versions 3.1 and earlier.
Since Microsoft cannot guarantee how MS-DOS will interact with future versions of Stacker, MS-DOS 6.2 Setup was not designed to detect and install over versions of Stacker later than 3.1.
STAC Electronics has released Stacker version 3.11; however, the box and disks still indicate version 3.1. You can tell the difference between Stacker 3.1 and 3.11 by the file dates and sizes. The file date for Stacker version 3.11 is 9/08/93, and the files are marked with the time 3:11 A.M. The problems described above occur with Stacker 3.11.
