Aptiva - Restarting in MS-DOS Mode under Windows 95
Applicable to: United States
While most software programs will run well under Windows 95 with no additional configuration, some MS-DOS based programs, most notably MS-DOS based games, may run slowly, or not at all when started from Windows. To accommodate these DOS games and applications, Windows 95 includes a special operating mode known as MS-DOS Mode which provides a native MS-DOS environment under which the DOS programs can run.
On Aptiva systems with Windows 95 preloaded, IBM preloads start-menu icons that will reboot your computer in MS-DOS mode using a configuration suitable for most MS-DOS based games. The specific icons included with each of the various Aptiva model types are described below. In addition to the preloaded icons, you can also restart your computer in MS-DOS mode using the standard Windows 95 method. For systems that were upgraded to Windows 95, the standard method described below must be used.
1. Click "Start", "Shutdown", "Restart in MS-DOS Mode", and then click "Yes."
2. Windows will shutdown and the C:\WINDOWS\DOSSTART.BAT file will be processed. This file contains DOS commands that configure the MS-DOS environment for things like CD-ROM and audio support. If your DOS program does not function under the standard MS-DOS mode configuration, you can modify this file as directed by your software manufacturer. The DOSSTART.BAT files for the various Aptiva models are included below.
3. Once the DOSSTART.BAT file has been processed, a C:\> prompt appears. At this point you can follow the instructions included with your software for changing to the program's directory (usually a command like CD <Directory Name>), and starting the program.
Choose your Aptiva model:
2144/2168 (preloaded Win95 only)
2134/2176/2159 (except S80 and S90)
2161/2162 (and 2159-S80 and S90)
Aptiva models 2144 and 2168
The 2144 and 2168 model Aptivas include an option for restarting the computer in an MS-DOS mode configuration suitable for DOS based games.
1. Click "Start", "Programs", "Accessories", "Games". The "Games" roll-out menu will contain an icon for DOS Mode Games. This icon will restart the machine in MS-DOS mode, and it includes audio and CD-ROM drive support. There is no support for EMS or XMS memory.
2. When the DOS mode games icons is selected, the following message will be displayed:
"This program is set to run in MS-DOS mode and cannot run while other programs are running. All other programs will close if you choose to continue.
Do you wish to continue?"
Click "Yes" to restart the computer.
3. The system will restart and display a C:\WINDOWS> prompt. At this point you can follow the instructions included with your software for changing to the program's directory (usually a command like CD <Directory Name>), and starting the program.
4. When you have finished using the DOS mode, at the DOS prompt, type "Exit" and press the "Enter" key to return to Windows.
Note: IBM has made available a program that can be installed on your Windows 95 Mxx, Axx, and Cxx systems which will provide several different DOS memory configurations from an icon on your Windows desktop. The name of the file is BLUEBOOT.EXE. It can be downloaded from the IBM BBS at (919) 517-0001, or from the IBM website, http://www4.pc.ibm.com/aptips/sprtdsks.html. Executing this file will expand files to a floppy diskette. The floppy diskette will also contain a README.TXT file which contains instructions for installation to your hard drive.
Model 2144/2168 DOSSTART.BAT file:
@echo off
REM Notes: REM DOSSTART.BAT is run whenever you choose "Restart the computer
REM in MS-DOS mode" from the Shutdown menu in Windows. It allows
REM you to load programs that you might not want loaded in Windows,
REM (because they have functional equivalents) but that you do
REM want loaded under MS-DOS. The two primary candidates for
REM this are MSCDEX and a real mode driver for the mouse you ship
REM with your system. Commands that you want present in both Windows
REM and MS-DOS should be placed in the Autoexec.bat in the
REM \Image directory of your reference server. Please note that for
REM MSCDEX you will need to load the corresponding real-mode CD
REM driver in Config.sys. This driver won't be used by Windows 95
REM but will be available prior to and after Windows 95 exits.
REM REM This file is also helpful if you want to F8 boot into MS-DOS 7.0
REM before Windows loads and access the CD-ROM. All you have to do
REM is press F8 and then run DOSSTART to load MSCDEX and your real
REM mode mouse driver (no need to remember the command line parameters
REM for these two files.
REM REM - You MUST explicitly specify the CD ROM Drive Letter for MSCDEX.
REM - The string following the /D: statement must explicitly match
REM the string in CONFIG.SYS following your CD-ROM device driver.
LH MSCDEX /D:IBMCD001 /l:F LH MOUSE

Aptiva models 2176 and 2159 (not 2159-S80 & S90)
1. Click "Start", "Programs", "Accessories", "Games". The Games roll-out menu will contain the following icons:
DOS Mode Games -- This option will restart the computer in MS-DOS mode with audio and CD-DOM support.
DOS Mode Games -EMS -- This option will restart the computer in MS-DOS mode with audio and CD-ROM support. This configuration should be used with games that require expanded, or EMS memory.
DOS Mode Games -XMS -- This option will restart the computer in MS-DOS mode with audio and CD-ROM support. This configuration should be used with games that require extended, or XMS memory.
2. When one of the DOS mode games icons is selected, the following message will be displayed:
"This program is set to run in MS-DOS mode and cannot run while other programs are running. All other programs will close if you choose to continue.
Do you wish to continue?"

As a last effort, the customer can reboot the unit and look for the "Starting Windows95" statement in the upper left corner of the monitor. Upon seeing the statement, the customer will need to press teh F8 key. This will produce the Microsoft Windows 95 Startup Menu. Here the customer would choose option 6 "Command Prompt Only". Please note that this will not load all the drivers the customer may need to use the application.
