SUMMARY

Symantec has confirmed that using Norton Utilities version 6.0 Disk Monitor with Microsoft Windows 3.0 and MS-DOS 5.0 may generate the following error message: 

   Fragmented Conventional Memory, reboot and retry or run Windows in
   real mode.
This problem has been corrected in Norton Utilities version 6.01.

MORE INFORMATION

Disk Monitor is an MS-DOS level terminate-and-stay-resident (TSR) program that prevents data from being written to the hard disk without approval. Disk Monitor will load itself high if upper memory block support is available.

The Norton Utilities LOADHIGH routine installs itself just below the 640K line, which may result in memory conflicts, and that may give the above error message when Windows 3.0 tries to load in standard or enhanced mode.

To correct this problem, do one of the following:

  • Upgrade to Norton Utilities version 6.01.
  • If upper memory support is available, use the MS-DOS 5.0 LOADHIGH command to override Norton Utilities LOADHIGH routine. In the AUTOEXEC.BAT file, enter the following line: 

          loadhigh diskmon
  • Disk Monitor can be loaded into conventional memory through the AUTOEXEC.BAT file as follows: 

          diskmon /skiphigh
  • Because this problem does not occur in the Microsoft Windows operating system version 3.1, another solution is to upgrade to Windows 3.1.
