MS-DOS DoubleSpace Conversion Kit for MS-DOS Upgrade & Step-Up
(The Conversion Kit is Located on the Supplemental Disk)

--------------------------------------------------------------------
The information in this article applies to:
 
 - Microsoft MS-DOS operating system version 6.22
--------------------------------------------------------------------
 
SUMMARY
=======
 
This article describes the Microsoft DoubleSpace Conversion Kit
(DBLCONV.EXE) and how to obtain and install it. The DoubleSpace Conversion
Kit enables you to convert DoubleSpace-compressed drives to DriveSpace
format. DBLCONV.EXE is a self-extracting executable file that contains the
following files:
 
   DRVSPACE.MR1
   README.TXT
   SETUP.EXE
   DBLCDESC.TXT
 
NOTE: If you installed MS-DOS 6.22 Step-Up, you should already have the
DRVSPACE.MR1 file in your DOS directory and therefore do not need to obtain
this conversion kit.
 
MORE INFORMATION
================
 
Description
-----------
 
The DoubleSpace Conversion Kit provides the DRVSPACE.MR1 file. If you used
MS-DOS 6 or 6.2 before installing MS-DOS 6.22, the DRVSPACE.MR1 file
enables MS-DOS to read data stored in the DoubleSpace compression format
even if the DoubleSpace driver (DBLSPACE.BIN) is not loaded in memory.
 
DRVSPACE.MR1 makes it possible to:
 
 - Convert DoubleSpace-compressed drives to DriveSpace format.
 
 - Use DriveSpace to mount and read DoubleSpace-compressed drives.
 
 - Use MS-DOS 6.22 ScanDisk to check and repair DoubleSpace-compressed
   drives and compressed volume files (CVFs), even if DBLSPACE.BIN is not
   loaded in memory.
 
 - Use MS-DOS 6.22 Backup for MS-DOS to restore backups created with MS-DOS
   6 or 6.2 Backup for MS-DOS or Windows, even if DBLSPACE.BIN is not
   loaded in memory.
 
IMPORTANT: DRVSPACE.MR1 works in conjunction with the MS-DOS DBLSPACE.BIN
file. If you did not install MS-DOS 6.22 over MS-DOS 6.0 or 6.2, you do not
have DBLSPACE.BIN and therefore cannot take advantage of the DoubleSpace
Conversion Kit functionality.
 
For information about converting DoubleSpace-compressed drives to
DriveSpace format, type "help dblspace" (without the quotation marks) at
the MS-DOS command prompt after you upgrade to MS-DOS 6.22, and then choose
the Notes button.
