1.0 Before installing Windows 95:
Before you install Windows 95 on your ThinkPad, you may need to get updated software from IBM or Microsoft.

1.1. How to get the updated software from IBM:
IBM PC Company is providing the updated software through several channels as follows. It is suggested to get the latest software from those channels so that you can set up Windows 95 on your ThinkPad systems with the information described in this document.

<WWW server on Internet>
The home page for IBM PC Company file library index is;
http://www.us.pc.ibm.com/files.html

Select "IBM Portables, Notebooks, Laptops Files" to find the necessary software.

<FTP site>
The IBM PC Company FTP server address for mobile product software fixes and patches is;
ftp.pc.ibm.com/pub/pccbbs/mobiles

<CompuServe ThinkPad Forum>
Join CompuServe ThinkPad Forum (GO THINKPAD) and download the necessary software from the library.

<IBM PC Company Bulletin Board Service (BBS)>
Use a terminal emulation software and modem to connect the IBM PC Company BBS in the US. The phone number is;
919-517-0001.

<Nifty-Serve IBM Forum in Japan>
Go to Nifty-Serve FIBMJ Forum (GO FIBMJ or library #20) and get the necessary software (Japanese software only).

<PEOPLE BBS in Japan>
Go to WIN95.CC Forum (Library #5)and get the necessary software (Japanese software only).

If you cannot get the updated software from either one, please contact your IBM representative.

1.2. System program update (Flash BIOS update):
Before you install Windows 95, you are strongly recommended to get the following version of ThinkPad System Program Service Diskette and to update your flash BIOS. Otherwise, Windows 95 may not run as explained in this document. You need to follow the instructions provided by the system program service diskette very carefully to update your flash BIOS program. Your system could be damaged by incorrect operations during this system program update.

<Important!>
You need to update the flash BIOS prior to install Windows 95 on your ThinkPad. In case you have already installed Windows 95 and update the flash BIOS later, you may need to run "Add hardware Wizard" of Windows 95 once again. If some problem still persists, it is recommended to reinstall Windows 95 after the flash BIOS update.

1.3. Backing up your software and data:
IBM recommends that you use a diskette backup program on your system to create recovery diskettes of the preinstalled operating systems, device drivers and applications. In addition, IBM recommends that you back up all data files to disk before installing Windows 95.

1.4. Removing preinstalled software:
Removing OS/2 Warp:
If you purchase a SelectaSystem model and are using OS/2 Warp version 3, Windows 95 cannot be installed with OS/2 Warp dual boot configuration in the SelectaSystem. Therefore, if you wish to install Windows 95, OS/2 Warp should be removed from your system along with all the preinstalled OS/2 applications. "Uninstall OS/2" icon is available for you in "OS/2 Warp" program group folder on your Windows desktop screen of SelectaSystem configuration.

If you wish to continue using OS/2 Warp with Windows 95, you need to use OS/2 Warp Boot Manager. For more information, refer to Windows 95 SETUP.TXT file. It can be found on the Windows 95 disk 1 or the Windows 95 CD-ROM.

Removing ThinkPad Welcome Screen:
If you plan to install, or have already installed Windows 95 over the following ThinkPad systems with factory preinstalled software, you may encounter "Windows 95 Explorer Fault".

If you have this problem, or to avoid this problem, please take the following steps.
1. Edit your WIN.INI file located under C:\WINDOWS subdirectory. For example, type "E C:\WINDOWS\WIN.INI" and press ENTER from DOS command prompt.
2. In [windows] section, find the "load=" statement. Remove STRTSCR.EXE from the "load=" statement as follows.

<Example>
Your original WIN.INI
[windows]
:
load=C:\SCREENS\STRTSCR.EXE C:\THINKPAD\FUELWIN.EXE
:

Remove STRTSCR.EXE
[windows]
:
load=C:\THINKPAD\FUELWIN.EXE
:

3. After you remove STRTSCR.EXE, you will no longer see the ThinkPad Welcome screen. If you have already removed this
screen, nothing will be changed by removing STRTSCR.EXE.

2.0 ThinkPad 365 system Specific Instructions:
Before you proceed:
Prior to installing Windows 95, it is recommended to obtain the following diskettes from the IBM PC Co. WWW site or BBS:
Thinkpad 365 Video Features Diskette for Windows 95
Thinkpad 365 Audio Features Diskette for Windows 95
Thinkpad 365 Infrared Features Diskette for Windows 3.1/95
Additionally, if you intend to format the Hard Disk Drive in the Thinkpad prior to installing Windows 95, and install from a CD-Rom, it will be necessary to have the Thinkpad CD-Rom Device Driver diskette for DOS/Win to enable the CD-Rom prior to installing Windows 95.

Install and setup Windows 95 on ThinkPad:
The following diskette can either be made from the Diskette Factory applet preinstalled on your Thinkpad or obtained from the WWW/BBS.
- "ThinkPad Utility Diskette". This consists of EPP3NS.EXE, SUPASS.EXE, PHDISK.EXE and README.DOC.

If your ThinkPad 365 system is a Windows 95 preinstalled model, these drivers are already installed on your system:

PCMCIA Device driver:
Windows 95 comes with the integrated PCMCIA support. To use the Windows 95 PCMCIA support functions, refer to the Windows 95 documentation or on-line help.

If you want to use ThinkPad PC Card Director (or EasyPlaying), you still can use ThinkPad DOS PCMCIA device drivers. To install ThinkPad PCMCIA device drivers, follow the instructions in ThinkPad 365 User's Guide.

<Important!>
The Windows 95 installation program doesn't enable its own 32bit PCMCIA support automatically. If you already have a ThinkPad system with ThinkPad DOS/Windows PCMCIA software and install Windows 95 on the system, the Windows 95 installation program keeps the ThinkPad PCMCIA support software and you can keep using it.
