(250-0440/1/2/3/4/5/50/53)    Configuring for Games   Faxback Doc. # 33015

This article applies to the Aptiva 2144 M31, M51, M52, and M63 desktop
models, and the 2168 M41, M53, M55, M56, M57, M61, M62, M71, M72 mini-tower
models, which come pre-loaded with Windows 95 installed.  These files can
be used as a guide for other computers using Windows 95, but they will not
work correctly if you just copy them to your system.

These AUTOEXEC.BAT and CONFIG.SYS files have been edited to provide three
options when you boot your system.  The first option will load Window 95
using the original configuration with which your system came pre-loaded.
The second option will boot to the DOS prompt, and it provides expanded
memory for DOS games that require expanded memory.  The third option also
boots to the DOS prompt, but it has EMM386 disabled, which is required by
some newer DOS games.  You can run Windows 95 from the latter two options
by typing "WIN" at the DOS prompt.

You will need to change the MSDOS.SYS file to use the new files.  To do
this, select Start, then Programs, and then the MS-DOS prompt.  Type the
following commands at the DOS prompt:

CD \
ATTRIB -H -S -R -A MSDOS.SYS
EDIT MSDOS.SYS

When editing the file, change "BootGUI=1" to "BootGUI=0".  Then save the
file and exit the editor.  Type the following command to restore the
attributes of the MSDOS.SYS file:

ATTRIB +H +S +R +A MSDOS.SYS

Then reboot the computer to let the changes take effect.

NOTE: To get the most free memory in DOS, run FASTCFG at the DOS prompt,
and configure it to use the first option for Sound Blaster Pro emulation
and no modem.  This will remove a 50KB driver file that uses much of your
conventional or upper memory.

Here are the two files:
