Sept. 2, 1998
The purpose of this document is to assist you in installing
Microsoft Windows 95 on your ThinkPad 755CD,CE,CSE,CDV,CV,CX
computer. Please follow the steps in this document carefully.
This document assumes that you are installing the Microsoft
Windows 95 Upgrade from Windows 3.10 or Windows 3.11.
As with any significant change to your computer's operating
system or software configuration, you should be sure to backup
all important files including data files before proceeding.
BEFORE INSTALLING MICROSOFT WINDOWS 95
--------------------------------------
1. Obtain Necessary Diskettes
You will need the following diskettes to ensure that
the ThinkPad's BIOS, device drivers, and utilities
are at a level to support Windows 95.

2. Update System Programs (BIOS)
a. Detach your ThinkPad from any Dock or Port Replicator
and connect the AC Adapter.
b. Insert the System Program Service Diskette into the
diskette drive.
c. Power on the ThinkPad and follow the directions on
the screen.
Caution: If during the update you receive a Warning
that you are about to install system programs
that are "down level" from those already
installed, then your ThinkPad already has
a later version installed. In this case, you
should select "N" to not continue installing
System Programs, then exit the utility. Then
skip to Step 3.
3. Initialize CMOS
This step is necessary to ensure that Windows 95 starts
with all ThinkPad settings at default.
a. Power on the ThinkPad while pressing the F1 key. Hold
the key down until the Easy-Setup screen appears.
b. Click on Config, then on Initialize.
c. Click on OK, then on Exit.
d. Click on Restart, then on OK.
4. Is the OS/2 Operating System currently installed on
your ThinkPad?
YES => Continue to Step 5.
NO => Skip ahead to Step 8.
5. Do you wish to keep OS/2 on your ThinkPad?
YES => Continue to Step 6.
NO => Skip ahead to Step 7.
6. Boot Manager should be used to control which operating
system will be started on your ThinkPad. See the
Windows 95 SETUP.TXT file for more information. It
is located on Windows 95 Diskette 1 and on the Windows
95 CD in the \WIN95 directory. After you have reviewed
this document and understand what to do, perform the
necessary actions and then skip ahead to Step 8.
7. Remove OS/2 Warp.
Do you have a "Delete OS/2 Warp" icon (normally in the
"OS/2 Warp" Program Group)?
YES => Double click on the Delete OS/2 Warp icon in the
OS/2 Warp Program Group. Click Options, then
click Delete. Click OK for each of the two
warnings. OS/2 Warp will then be removed from
your ThinkPad.
NO => From Windows Program Manager, Click File, Run.
Then type:
"C:\OS2TOOLS\WARPREMV.EXE WARPREMV.TXT WARPREMV.LST"
and press Enter. Click Options, then click Delete.
Click OK for each of the two warnings. OS/2 Warp
will then be removed from your ThinkPad.
NOTE: If you are unable to remove OS/2 from your ThinkPad
using these techniques, then see the Windows 95
SETUP.TXT file, located on Windows 95 Diskette 1 and
on the Windows 95 CD in the \WIN95 directory.
8. Make backup copy of system files to be modified.
This installation procedure will require you to view and in
some cases modify your CONFIG.SYS, AUTOEXEC.BAT, and WIN.INI
files. Before proceeding, we recommend that you make a
backup copy of these files.
a. At the DOS C:\ prompt, type "MD C:\TP95PREP" and press Enter.
b. Type "CD \TP95PREP" and press Enter.
c. Type "COPY C:\CONFIG.SYS" and press Enter.
d. Type "COPY C:\AUTOEXEC.BAT" and press Enter.
e. Type "COPY C:\WINDOWS\WIN.INI and press Enter.
This will copy these system files to the C:\TP95PREP directory.
9. Remove STRTSCR.EXE (ThinkPad Welcome screens).
To avoid a possible "Windows 95 Explorer Fault" error
message, you should remove the STRTSCR.EXE from the
Windows WIN.INI file.
a. Start the Windows 3.1 NotePad application from the
Accessories Program Group.
b. Click File, Open. Then type "C:\WINDOWS\WIN.INI" and
press Enter.
c. Find the lines (near the top) that begin with "load="
and "run=".
d. If either line contains "C:\SCREENS\STRTSCR.EXE", then
delete this portion of the line. For example,
"load=C:\SCREENS\STRTSCR.EXE C:\THINKPAD\FUELWIN.EXE"
should be changed to:
"load=C:\THINKPAD\FUELWIN.EXE"
Or,
"load=C:\SCREENS\STRTSCR.EXE"
should be changed to:
"load="
e. After the change is made, click File, then Exit. Then
click "Yes" to save the change.
10. Remove unnecessary PCMCIA(**) SRAM, Flash, and ATA drivers.
If you are installing from CD or a network drive and you
plan to use the Windows 95 Integrated PCMCIA support
(recommended), you may want to first disable the PCMCIA
driver for SRAM, Flash, and ATA type PCMCIA cards. This
will remove the drive letters (usually D,E,F, and G)
reserved by the PCMCIA driver. These will not be reserved
when you install the Windows 95 Integrated PCMCIA support
later, so disabling this driver before installation of
Windows 95 will give you a consistent default installation
drive for any Windows 95 drivers you may install in the
future. To disable the PCMCIA SRAM, Flash, and ATA driver:
a. Edit the CONFIG.SYS (using Windows Notepad or another
editor.
b. Find any line that contains:
"DISKDRV.SYS"
Place a "REM " in front of this line so that it will
not be run. For example,
"DEVICEHIGH=C:\THINKPAD\DISKDRV.SYS"
should be changed to:
"REM DEVICEHIGH=C:\THINKPAD\DISKDRV.SYS"
c. Exit the editor and save the change.
11. Remove IBM Antivirus for DOS / Windows from the AUTOEXEC.BAT.
This is necessary since the IBM Antivirus for DOS / Windows
program is not supported in Windows 95. If you are using
other virus protection software, you should see the SETUP.TXT
file on the Windows 95 Diskette 1 or in the \WIN95 directory
on the Windows 95 CD for information before continuing with
installation.
a. Edit the AUTOEXEC.BAT (using Windows Notepad or another
editor.
b. Find any line that contains:
"IBMAVDR.BAT"
Place a "REM " in front of this line so that it will
not be run. For example,
"CALL C:\DOS\IBMAVDR.BAT C:\DOS\"
should be changed to:
"REM CALL C:\DOS\IBMAVDR.BAT C:\DOS\"
c. Exit the editor and save the change.
INSTALLING WINDOWS 95
---------------------
12. Install Windows 95 Upgrade.
a. Shutdown Windows and press Ctrl-Alt-Delete to restart
the ThinkPad to make changes in the previous steps active.
b. Before starting Windows 95 Setup, read the IMPORTANT items
below. Then start Windows 95 Setup from Windows and follow
the directions on the screen.
IMPORTANT: When Windows 95 asks if you want it to detect the
Sound, MIDI, or Video Capture Card, do not put a
check mark in the box beside "Sound, MIDI, or Video
Capture Card". We will install the Mwave for
Windows 95 drivers and the Enhanced Video drivers
after SETUP is complete.
IMPORTANT: When Windows 95 Setup Wizard shows the Get Connected
screen and asks if you would like to install support
for:
- The Microsoft Network

h. You should no longer see the error message.
5. Device Support in MS-DOS Mode
If you're ThinkPad is a 755CD or 755CDV and you want to use
the internal CD ROM in MS-DOS Mode, see the Item "Adding
Internal CD ROM Support for MS-DOS Mode" below for
instructions on creating a unique CONFIG.SYS and AUTOEXEC.BAT
for MS-DOS Mode.
If you're ThinkPad is a 755CE,CSE,CV,CX then it is usually not
required to use a unique CONFIG.SYS and AUTOEXEC.BAT for
device support in MS-DOS mode. Instead, the CONFIG.SYS and
AUTOEXEC.BAT used to start Windows 95 can be used. In this
case, when you select to restart in MS-DOS mode, Windows 95
will exit to DOS and an additional DOSSTART.BAT will be run.
For device support, edit C:\WINDOWS\DOSSTART.BAT and ensure
that the following lines or similar are present:
SET BLASTER=A220 I5 D1
LOADHIGH C:\DOS\MOUSE.COM /Y
LOADHIGH C:\CDROM\MSCDEX.EXE /D:xxxxxxx /M:15
CALL MWAVE START NOSHOW
NOTES:
a. SET BLASTER entry should match settings for the Mwave DSP
as set by ThinkPad Setup, DSP, Sound Blaster(**) section
for I/O Address, IRQ, and DMA. The values above are the
default values and should work if you initialized CMOS
as specified in Step 3 above. Use FASTCFG command to
confirm Mwave DSP Hardware settings for Sound Blaster.
b. Path of your DOS Mouse driver may be different. You may
need to locate your MOUSE.COM and specify the correct
path.
c. MSCDEX is only needed if you have a CD ROM drive (for
example SCSI CD ROM in Dock 1 or Dock 2) that you will
use in MS-DOS mode. (Substitute the name of your CD ROM
driver specified in CONFIG.SYS after the "/D:" parameter
in place of the "xxxxxxxx" on the MSCDEX line).
d. CALL MWAVE START NOSHOW will activate the Mwave DSP in
MS-DOS mode to provide sound or modem support. Use
FASTCFG command to setup the Mwave DSP in MS-DOS mode.
6. 755CD and 755CDV Only => Adding Internal CD ROM Support for
MS-DOS Mode
If you need to use your internal CD ROM in MS-DOS mode, you
must create an alternate startup configuration (CONFIG.SYS
and AUTOEXEC.BAT) that will be used when restarting to
MS-DOS Mode. To create an alternate startup configuration,
perform the following steps from the Windows 95 Desktop:
a. Double click "My Computer", then "(C:)". Then double click
the "Windows" folder and find the "Exit To Dos" icon. With
the right mouse button, click this icon. This should open a
selection window.
b. Choose "Properties" from the selection window.
c. "Exit To Dos Properties" Window should now be displayed.
Select "Program", then "Advanced". The "Advanced Program
Settings" window should be displayed. Ensure that the MS-DOS
mode box is checked.
d. Click the "Specify a new MS-DOS configuration" circle.
You may now add DOS statements that will be loaded when the
system is started in MS-DOS Mode. Add the following lines
to CONFIG.SYS for MS-DOS Mode and AUTOEXEC.BAT for MS-DOS
Mode if not already listed. These will also ensure that
you have Enhanced Video, Mwave Audio, a Mouse Driver, and
EMS memory required for some DOS games.
"CONFIG.SYS for MS-DOS mode:"
DEVICE=C:\WINDOWS\HIMEM.SYS
DOS=HIGH,UMB
DEVICE=C:\WINDOWS\EMM386.EXE RAM FRAME=E000
DEVICEHIGH=C:\MWW\MANAGER\MWD50430.EXE
DEVICEHIGH=C:\CDROM\IBMTPCD.SYS /D:TPCD001 /P:170 /R
DEVICE=C:\V7320\V7320MGR.EXE
DEVICE=C:\V7320\V7320APM.EXE
"AUTOEXEC.BAT for MS-DOS mode"
SET PATH=C:\;C:\THINKPAD;C:\MWD\MANAGER;C:\MWW\DLL;
SET LIBPATH=C:\MWD\MANAGER
SET MWPATH=C:\MWD\MANAGER;C:\MWD\MWGAMES
SET MWROOT=C:\MWD
SET IPF_PATH=C:\IPFWIN
SET PS2MSG=C:\THINKPAD\PS2.MSG
SET BLASTER=A220 I5 D1
LOADHIGH C:\CDROM\MSCDEX.EXE /D:TPCD001 /M:15
LOADHIGH C:\DOS\MOUSE.COM /Y
CALL MWAVE START NOSHOW
e. After the changes are made, click "OK" and "OK" again to
close the open windows. This configuration will now be
used when you restart your system in MS-DOS mode.
IMPORTANT:
----------
To ensure that the Internal CD ROM is recognized in
Windows 95 after restarting to MS-DOS Mode with internal
CD ROM support, you will have to do the following:
- When you are ready to exit MS-DOS mode and return
to Windows 95, POWER OFF the ThinkPad 755CD,CDV.
(The ThinkPad must be POWERED OFF to be completely
reset after the Real Mode CD ROM Driver (IBMTPCD.SYS)
has been active. Otherwise, Windows 95 will not
recognize the Internal CD ROM drive.)
- Power On the ThinkPad. The following message will
be displayed:
Windows 95 is now starting your MS-DOS-based program.
Press ESC now to cancel MS-DOS mode and restart Windows 95...
- While this message is displayed, press ESC and
Windows 95 will start and the Internal CD ROM
will be recognized.
NOTES:
a. SET BLASTER entry should match settings for the Mwave DSP
as set by ThinkPad Setup, DSP, Sound Blaster section for
I/O Address, IRQ, and DMA. The values above are the
default values and should work if you initialized CMOS
as specified in Step 3 above. Use FASTCFG command to
confirm Mwave DSP Hardware settings for Sound Blaster.
b. Path of your DOS Mouse driver may be different. You may
need to locate your MOUSE.COM and specify the correct
path.
c. CALL MWAVE START NOSHOW will activate the Mwave DSP in
MS-DOS mode to provide sound or modem support. Use
FASTCFG command to setup the Mwave DSP in MS-DOS mode.
7. Removing DOS Startup Menu in CONFIG.SYS
If you are currently using a Startup Menu in CONFIG.SYS,
you may want to skip this menu now that Windows 95 is
installed. Use of this type of startup menu in CONFIG.SYS
is usually not required in Windows 95 since Windows 95:
- Is less prone to Conventional Memory Constraints.
- Can automatically develop configurations for
Docked and Undocked states.
- Can Restart to MS-DOS Mode when required.
If you would like to skip this menu during startup, do the
following:
a. At the DOS Prompt, type Edit C:\CONFIG.SYS and press Enter.
b. In the [MENU] section of CONFIG.SYS, find the line that
begins with "MENUDEFAULT=". This line specifies which
DOS menu selection will be used as default, and the time
to wait before starting without any input.
c. If there is a comma followed by a number at the end of
this line, change the number to 0.
d. If there is no comma and number at the end of this line,
add the following at the end of the line with no space
after the configuration name:
,0
e. Click File, then Exit, then Yes to save the change. At your
next restart, Windows 95 should use the default startup in
your CONFIG.SYS without displaying the menu.
8. Configuring ThinkPad Hardware Devices in Windows 95
If you need to change any of your hardware device settings
such as I/O address, IRQ, or DMA, you need to use the proper
utility for the device you wish to configure. In some cases
you will need to use Windows 95 Device Manager and in some
cases you will need to use the ThinkPad Setup utility. See
the table below for the utility to use for each device:
Hardware Device To Change Resource Settings
--------------- ---------------------------
Mwave DSP Windows 95 Device Manager
- Sound Blaster Windows 95 Device Manager
- MPU-401 MIDI Windows 95 Device Manager
- Modem Windows 95 Device Manager
Infrared ThinkPad Setup, Infrared
Serial ThinkPad Setup, Serial
Parallel ThinkPad Setup, Parallel
Enhanced Video ThinkPad Setup, Video Controller
NOTE: A Red X beside a device in Device manager only means
that the device is disabled in the current configuration.
NOTE: The Enhanced Video Device on the 755CD and 755CDV models
is listed as an "Unknown Device" in the Windows 95 Device
Manager, but still works properly.
9. Horizontal Stripe Following Mouse Pointer on External CRT
When you attach a high resolution external CRT and switch
between a MS-DOS full screen session and the Windows 95
desktop, you may see a horizontal line that follows the
mouse pointer. If this happens, perform the following steps
to correct the problem:
a. Double click My Computer, then Control Panel, then System.
b. Click on the "Performance" tab, then click the "Graphics"
button.
c. Move the "Hardware acceleration" slider one notch to the left.
d. Restart Windows 95 when prompted.
10. 755CD and 755CDV Only => Asymetrix(**) Digital Video Producer(**)
Capture Tool
If you are unable to open the Options, Video Format menu in
the Digital Video Producer Capture Tool, please do the following:
a. Close Digital Video Producer Capture and close Digital Video
Producer if open.
b. Restart Digital Video Producer Capture Tool (but not Digital
Video Producer).
c. Retry Options, Video Format.
d. If it still fails, close Digital Video Producer again and
restart Digital Video Producer again. Then retry Options,
Video Format.
Currently, the Options, Video Format menu only works on every
other start of Digital Video Producer Capture in Windows 95.
It does not open at all when the Capture tool is started from
the tool menu of the main Digital Video Producer. (The capture
tool must be started directly).
NOTE: This problem may be fixed in a future release of the
IBM ThinkPad 755CD Enhanced Video Features (version
higher than 1.20).
