ISSUE/PROBLEM
If the AutoCAD swap file is created on a SuperStor compressed
partition, it is given maximum compression ratio of 16:1.  When
AutoCAD then creates other working files on the compressed
partition, they prevent the swap file from expanding as necessary,
resulting in an error from the Virtual Memory Manager (VMM).

SOLUTION
Create the AutoCAD swap file on an uncompressed partition.  Users
ought to refer to their AutoCAD documentation for instructions on
this.  Here are the steps that we have found to work: 

1) Execute a configuration program called CFIG386.EXE.  The
necessary command is: CFIG386 ACAD.EXE -SWAPDEFDISK x:  (where x:
is the drive designation of the uncompressed partition).

2) It is also possible to designate a directory in which the file 
should reside by entering:  CFIG386 ACAD.EXE -SWAPDIR x:\temp 
(where x:\temp is the drive and directory on the uncompressed
partition).

There needs to be about 5 Megabytes of free disk space on the
uncompressed partition before CFIG386 can make these changes.  If
this is not the case, it will be necessary to backup the data on
the compressed partition, remove the compressed partition, and
recreate it, leaving the uncompressed partition about 5 MB larger
than it currently is.

Other configuration tips regarding AutoCAD 11 are as follows:
(1) set FILES=100 
(2) set FCBS=48,8 
(3) set BREAK=OFF.
These changes are to the CONFIG.SYS file.
