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.

The RAMDRIVE.SYS line in the CONFIG.SYS file should precede the DBLSPACE.SYS line
or the RAMDrive will receive a different drive designation from what it was
before. This can become a problem if you have many batch files referencing the
RAMDrive. For example, if your batch files reference drive D and it becomes
drive I after DoubleSpace is installed, your batch files will not work.

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

The drives used for DoubleSpace are selected from the last available drive
rather than the first available drive. If RAMDRIVE.SYS precedes the DBLSPACE.SYS
line, then the RAMDrive's drive letter comes right after the last physical
drive. For example, if you have a drive C and a floppy disk drive A, then the
RAMDrive is assigned the letter D.

If the RAMDRIVE.SYS line comes after the DBLSPACE.SYS line, DoubleSpace has
already allocated all the drive letters between drive C and its host drive
(probably drive H) so the RAMDrive is assigned letter I.

For information on how DoubleSpace assigns host drive letters, query on the
following words in the Microsoft Knowledge Base:

  doublespace and assigns and host

For more information on RAMDrive, type "help ramdrive.sys" (without the quotation
marks) at the MS-DOS command prompt and press ENTER.
