SYMPTOMS
========

After you start the Stacker conversion process and DoubleSpace reboots your
computer, you may receive the following error message:

  AN ERROR OCCURRED while attempting to convert Stacker volume c:\stacvol.dsk
  to DoubleSpace format. There is not enough conventional memory.

CAUSE
=====

This problem occurs when DoubleSpace reboots your computer and there is
insufficient memory to convert your Stacker volume file (SVF) to a DoubleSpace
compressed volume file (CVF) due to the size of your SVF.

RESOLUTION
==========

You can work around this problem by using the following procedure:

NOTE: Reboot your computer and try to run the Stacker conversion routine after
each step.

1. Place DBLSPACE.SYS in a parallel directory on the host drive. For example, if
  C:\DOS contains your MS-DOS files, and your host drive is D, type "xcopy
  c:\dos\dblspace.sys d:\dos\" (without the quotation marks) at the MS-DOS
  command prompt and then press ENTER.

2. Edit the CONFIG.SYS file and ensure the DEVICE commands for HIMEM.SYS and, if
  present, EMM386.EXE are placed before the first DEVICE=C:\DOS\DBLSPACE.SYS
  line.

3. Edit the CONFIG.SYS and AUTOEXEC.BAT files and remark out unneeded device
  drivers and terminate-and-stay-resident (TSR) programs using the REM command.

4. Defragment the host drive for the Stacker-compressed drive. To do this:

  a. Copy ATTRIB.EXE to the host drive.

  b. Copy DEFRAG.EXE to the host drive.

  c. Unmount the Stacker-compressed drive.

  d. Clear the file attributes on the SVF. For example, type "attrib -r -s -h
     stacvol.*" (without the quotation marks) at the MS-DOS command prompt and
     then press ENTER.

  e. Run DEFRAG /H <host drive> to fully defragment the Stacker host
     drive.
