-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft MS-DOS operating system versions 6.0, 6.2, 6.22 
-------------------------------------------------------------------------------

SUMMARY
=======

This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace.
For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.

STAC Electronics Stacker 3.1 modifies the DBLSPACE.BIN file to allow access to
Stacker-compressed volumes; however, Stacker does not change the DBLSPACE.BIN
filename.

MORE INFORMATION
================

The command SYS.COM, which is supplied with Microsoft MS-DOS 6.x, normally
generates the following four files:

  IO.SYS
  MSDOS.SYS
  COMMAND.COM
  DBLSPACE.BIN

If Stacker 3.1 is present and you use SYS.COM to make a bootable floppy disk, the
Stacker 3.1 version of DBLSPACE.BIN is generated and placed on the disk along
with the other system files. If you use this floppy disk, a STAC Electronics
copyright message is displayed during startup. If you boot your MS-DOS 6.0 or
6.2 system with this disk and DoubleSpace is installed, the drive cannot mount
because DBLSPACE.BIN is now controlled by Stacker 3.1.

NOTE: Microsoft can neither guarantee nor support the functionality of the
Stacker DBLSPACE.BIN file.

If Stacker 3.1 is present, the only reliable methods to create an MS-DOS 6.0 or
6.2 startup disk are:

- Run SETUP /F using the MS-DOS 6.0 or 6.2 Upgrade disks.

-or-

- Copy the DBLSPACE.BIN file found on the MS-DOS 6.0 or 6.2 Uninstall disk to
  the bootable floppy disk.

Stacker 3.1 is manufactured by STAC Electronics, a vendor independent of
Microsoft; we make no warranty, implied or otherwise, regarding this product's
performance or reliability.
