    your CONFIG.SYS and restore the DEVSWAP.COM line.  After you do 
    this, you must edit your CONFIG.SYS and AUTOEXEC.BAT to restore the 
    drive specifications to what they were before; e.g. change all 
    references to drive D: to drive C: and all references to drive C: to 
    drive D:.  As mentioned above, if SSTORDRV.SYS is being loaded high, 
    you must change  it to load low because it won't work when loaded 
    high.  Reboot again.  You are now getting the most out of your 
    conventional memory.

AN ALTERNATIVE METHOD FOR USING OPTIMIZE WITH DR-DOS'S SUPERSTOR

Start with QEMM386.SYS (or QEMM.SYS or QRAM.SYS) on an uncompressed drive.  
Leave about one megabyte of space on the uncompressed drive.  No other 
Quarterdeck files but QEMM386.SYS (or QEMM.SYS or QRAM.SYS) are needed from 
the QEMM directory.

The first line in DCONFIG.SYS, which is the config.sys first read on bootup, 
should be DEVICE=C:\QEMM\QEMM386.SYS RAM, assuming that QEMM386.SYS is in the 
QEMM directory of the same drive that DCONFIG.SYS is on.  The entire 
DCONFIG.SYS will normally be

DEVICE=C:\QEMM\QEMM386.SYS RAM
DEVICE=C:\DRDOS\SSTORDRV.SYS
DEVICE=C:\DRDOS\DEVSWAP.COM
CHAIN=C:\CONFIG.SYS

Now, move DEVICE=C:\QEMM\QEMM386.SYS to the CONFIG.SYS chained to from 
DCONFIG.SYS. 

MAKE CERTAIN THAT THE QEMM DEVICE LINE IS NO LONGER IN DCONFIG.SYS.

Run OPTIMIZE.

When you're through running OPTIMIZE, move the DEVICE=C:\QEMM\QEMM386.SYS line 
back to the DCONFIG.SYS file. 

That's all there is to it.  You don't have to get rid of DEVSWAP or change the 
drive mappings. 

GENERAL CONSIDERATIONS

    LASTDRIV.COM 
         Lastdriv.com is a program that comes with QEMM-386, QEMM- 
    50/60, and QRAM that allows drive specifiers to be loaded 
    at the DOS prompt.  This allows QEMM-386, QEMM-50/60, and QRAM to 
    load them high.  DR-DOS 6 does not seem to recognize drive 
    specifiers loaded by Lastdriv.com, whether loaded high or low.
         DR-DOS loads its drive specifiers high by itself, when 
    the HIDOS=ON instruction is used, so Quarterdeck's 
    Lastdriv.com is not necessary to load drive specifiers high.

    STACKS 
        Unlike MS and IBM DOS, there are no DOS stacks in DR-DOS 6.  
    There are programs that may malfunction when DOS does not allocate 
    stacks, such as Ventura running in QEMM-386 with Stealth.  Such 
    users must contact DR to request that they add a STACKS feature to their 
    operating system. 

QEMM-386
     QEMM-386 provides all the memory management capabilities of EMM386.SYS, 
plus creating more High RAM through the Stealth feature, having OPTIMIZE to 
automatically configure your system to use that High RAM most efficiently, and 
Manifest, the system diagnostic utility.  Microsoft Windows can be run in 
standard mode with QEMM-386 while QEMM creates High RAM and provides Expanded 

memory.  Windows cannot run in standard mode with DR-DOS's EMM386.SYS if it 
creates any High RAM, and its Expanded memory manager is turned off while you 
are in standard mode.

QRAM
     DR-DOS creates UMBs on the same hardware that QRAM creates them on: EMS 
cards that map address space outside the page frame and above conventional 
memory, and the same varieties of ShadowRAM (NEAT, LEAP, SCAT, and AT/386) so 
that QRAM is not necessary to create UMBs or load anything high on DR-DOS.  
QRAM does come with OPTIMIZE, which allows you to configure your config.sys 
and autoexec.bat automatically so that the most possible resident programs are 
loaded high and Manifest, Quarterdeck's system diagnostic utility.

QEMM-50/60
     DR-DOS comes with an Expanded Memory Manager for XMA boards which creates 
Expanded Memory on some of the same cards that QEMM-50/60 works on.  It does 
not create any UMBs (High RAM) though so users of these boards need QEMM-50/60 
in order to load programs high.  

VIDRAM
     DR-DOS comes with a program called MEMMAX that allows the user to turn 
off the extending of conventional memory into the video area if previously 
mapped by their memory manager.  This feature does not work without their 
memory manager.  VIDRAM works just fine.  Users of any Quarterdeck memory 
manager or enhancer should use VIDRAM instead of MEMMAX.

MANIFEST
        1)  For purposes of identifying its level of API support, DR-DOS 
    reports itself as version 3.31 of DOS.  It loads an environment
