          TITLE:  Configuring DR DOS for Falcon 3.0
   DOCUMENT ID#:  FYI-M-1614
           DATE:  29DEC92
        PRODUCT:  DR DOS
PRODUCT VERSION:  6.0
     SUPERSEDES:  06FEB92

        SYMPTOM:  Trouble configuring Falcon 3.0

  ISSUE/PROBLEM:  

Falcon 3.0 is compatible with DR DOS 6.0. There are, however, very
important memory requirements that must be met for this application
to properly run. 

Falcon requires a minimum of 600K (614,400 bytes) of memory to run.
This can make it difficult for some users with SuperStored drives
to access the program. If this is the case it is possible to
install the application to a non-compressed drive and create an
alternate CONFIG.SYS (or DCONFIG.SYS) that does not load the
SuperStor driver. 

Other TSR's should also be avoided. One of the advantages of DR DOS
6.0 is its ability to run alternate configuration files. Additional
configuration programming can be found in the DR DOS 6 users guide
and in FYI-M-1113.

The installation program may display an error that indicates the
computer only has 575K free and more memory needs to be made
available. DR DOS is detecting that the installation program may be
exepacked and is using up the first 64K of base memory before
launching the program. Users should ignore this message and
continue. If the install program returns to a DOS prompt try using
the command "MEMMAX -L" and restarting the install program. In some
cases users may see a screen that contains control characters and
asks for a Y/N response. Ignore the unreadable portion and answer
"N" and the installation will proceed normally. Remember to use the
command "MEMMAX +L" to free up locked memory before running Falcon.

*There may also be an additional problem for users who have single
floppy computers. When the installation program is "Decompressing
Files" users may see  a message that says, "Insert diskette for
drive (A or B) and press any key when ready." Do not remove the
floppy from the drive but merely strike any key. This may require
repeated strikes to continue and will have to be done for every
disk. 

*If the installation program freezes or gives an error message
users should delete all installed files and the Falcon directory
and reinstall.


*If a user is unable to use the keyboard to select buttons in the
interface or the cockpit functions while flying around, the user
may need to add "BREAK=ON" to the CONFIG.SYS. If this fails to
work, unplug the keyboard from the computer and then plug it back
in again.


*Users need to be sure that they are using the latest version of
their mouse driver. Genius mice can be a possible problem and need
to be using a version 9.06 driver.


*If digitized radio messages are playing, be sure that there is at
least 480K (491,520 bytes) of EMS memory for those sounds. This
will require a computer of at least 2 MB of RAM. All other sound
effects will be available without EMS memory. To determine the
amount of EMS memory available with DR DOS type "MEM" at a DOS
prompt.


*Minimum System Requirements for Falcon 3.0

. 12MHz 80286 IBM (or compatible) computer or IBM PS/2 Model
  30-286 or higher

. 1 MB of RAM

. DOS 5.0 or higher

. Hard drive with at least 11MB free space

. VGA graphics card and VGA color monitor

. One 1.2MB 5.25 in disk drive or one 1.44MB 3.5 in disk drive
