DoubleDisk and 386MAX

This information explains how to install DoubleDisk or DoubleDisk Gold
on a system that has 386MAX or BlueMAX, versions prior to 6.03,
installed, and how to install 386MAX or BlueMAX on a system that
currently has DoubleDisk installed.  Though 386MAX is used for all
examples, the following information is applicable to BlueMAX as well.
Use the information in the README file for version 7 or later of
386MAX and BlueMAX.


Installing DoubleDisk on a 386MAX system

This information explains how to install DoubleDisk or DoubleDisk Gold
if either 386MAX or BlueMAX is already present on the system.

* Uninstall 386MAX.  Go to the 386MAX directory and type STRIPMGR C:
/ST (where C:  represents your bootable drive) and press < ENTER >.
This removes all references to 386MAX in the CONFIG.SYS and
AUTOEXEC.BAT files.  If you allowed 386MAX to install QCACHE on your
system, place a REM statement in front of the line in your
AUTOEXEC.BAT that loads QCACHE.

* Do not delete any 386MAX files.

* Reboot your system.

* Install DoubleDisk per their directions.	After you have installed
DoubleDisk, run ALL of your applications to ensure that they work
correctly.	Do not continue if DoubleDisk installation does not
complete as expected or if you have problems using your applications.

* If you are having problems at this point, consult your DoubleDisk
documentation and/or their technical support to get your system in
working order.

Reinstall 386MAX using the instructions below only after successful
DoubleDisk installation and implementation.


Installing 386MAX on a DoubleDisk system

This information explains how to install 386MAX or BlueMAX if
DoubleDisk is already present on the system.

* Look in C:\AUTOEXEC.BAT for a line that looks similar to:

		C:\DUBLDISK\ACTIVATE.EXE

* Write down the options used on the ACTIVATE.EXE line in
C:\AUTOEXEC.BAT.

* Edit AUTOEXEC.BAT to place REM in front of the ACTIVATE.EXE line.
This disables DoubleDisk's drive swapping and does not allow access to
the compressed volume.	ACTIVATE.EXE is not a TSR and is not required
for Maximize.

* Reboot.  If DoubleDisk prompts you to update the AUTOEXEC.BAT file,
select YES to make the changes and YES again to reboot the system.

* On the second reboot, watch for programs that normally load AFTER
the ACTIVATE.EXE line but no longer load at all.  If the program that
does not load looks like it is a TSR, you need to copy it and its
supporting files to the C:\ drive.

To access the compressed volume so that you can find the missing
programs and copy them to C:, type

	C:\DUBLDISK\ACTIVATE (options)

where (options) refers to the options you noted in step 1. This
activates the compressed drive and swap drive letters.

* Run Install and Maximize as usual.  Since any compressed drives are
not active at this point, the programs do not require any special
treatment.

If you have any problems installing 386MAX on your system, type
PREINST<ENTER> at the command line in the 386MAX subdirectory to
return your CONFIG.SYS and AUTOEXEC.BAT to the active configuration
prior to the installation of 386MAX.  If you have problems after
starting Maximize, PREMAXIM returns your CONFIG.SYS and AUTOEXEC.BAT
to the configuration prior to the last pass of Maximize.  PREMAXIM
runs automatically if Maximize does not run to completion.

* When Maximize completes, edit the C:\AUTOEXEC.BAT file and remove
the REM statement from the ACTIVATE.EXE line.  Reboot the system.

* Create a 386MAX directory on the UNCOMPRESSED drive.	Copy the
following files into the directory:

	386MAX.VXD
	386LOAD.CFG
	386LOAD.COM

To determine the name of the compressed drive, look at the
ACTIVATE.EXE line.	For example, if ACTIVATE.EXE is loaded with the
line:

	C:\DUBLDISK\ACTIVATE.EXE A C0=D , S C=D

the option C=D will switch drive C with drive D. Drive C, in this
case, is the compressed volume.


A Note to those using Microsoft Windows

If you have installed or updated DoubleDisk and receive the following
error message upon entering Windows:

	  386MAX VxD Error V1014:  Disk Cache or other File I/0
				   Software Using EMS Memory

remove the /A option on the line that loads DUBLEDISK.SYS in your
CONFIG.SYS.  The best way to do this is to run the DUBLEDISK
configuration program from your hard disk as described in the
DoubleDisk manual.
