Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

                                DRVSPACE.SYS
 
Determines the final memory location of DRVSPACE.BIN, the part of MS-DOS
that provides access to your compressed drives.
 
When you start your computer, MS-DOS loads DRVSPACE.BIN along with other
operating system functions, before carrying out the commands in your
CONFIG.SYS and AUTOEXEC.BAT files. DRVSPACE.BIN initially loads in
conventional memory because it loads before device drivers that provide
access to upper memory.
 
When you run DriveSpace Setup, it adds a command for DRVSPACE.SYS to your
CONFIG.SYS file.
 
Syntax
 
    DEVICE = [drive:][path]DRVSPACE.SYS /MOVE [/NOHMA]
 
    DEVICEHIGH = [drive:][path]DRVSPACE.SYS /MOVE [/NOHMA]
 
Switches
 
/MOVE
    Moves DRVSPACE.BIN to its final location in memory.
 
    Initially, DRVSPACE.BIN loads at the top of conventional memory. After
    MS-DOS finishes carrying out the commands in the CONFIG.SYS file, it
    moves DRVSPACE.BIN to the bottom of conventional memory. When
    DRVSPACE.SYS is loaded by using the DEVICE command, it moves
    DRVSPACE.BIN from the top of conventional memory to the bottom. This can
    be useful for avoiding conflicts with programs that are loaded from the
    CONFIG.SYS file and require access to the top of conventional memory.
 
    When DRVSPACE.SYS is loaded by using the DEVICEHIGH command,
    DRVSPACE.BIN moves to upper memory, if available. Moving DRVSPACE.BIN to
    upper memory makes more conventional memory available.
 
/NOHMA
    Prevents DRVSPACE.SYS from moving a portion of DRVSPACE.BIN to the high
    memory area (HMA).
 
    If MS-DOS is loaded into the HMA, DRVSPACE.SYS moves a  portion of
    DRVSPACE.BIN to the HMA (if there is enough room in the HMA). Use this
    switch if you do not want DRVSPACE.BIN to use the HMA. (It is not
    necessary to use this switch if you upgraded to MS-DOS 6.22 from MS-DOS
    6.0.)
 
Parameter
 
[drive:][path]
    Specifies the location of the DRVSPACE.SYS file.
