2.7  Initial Software Load
After unpacking and setting up the notebook for the first time, you must perform an 
initial software load that takes approximately 30 minutes.
Because of the way Windows 95 structures its files, stopping in the middle of the setup 
process can cause irreversible file damage.
AC Adapter DC-IN Connector 
						

							2-15   Installation
Before starting the initial software load process, ensure that you have the following:
¨Extensa 900 User’s Guide - Contains latest software installation instructions.
¨AC Adapter/Access to AC power - Although the battery pack may have some 
charge, it may be insufficient for the entire set up. Loss of power during setup 
can cause irreversible file damage.
¨Certificate of Authenticity - You will need to enter the number from your 
Windows 95 Certificate of Authenticity during Windows 95 Setup. This 
certificate is part of the Windows 95 documentation kit. You need this number 
even if you are installing Windows for Workgroups.
¨Language - During initial setup you choose the following:
- Language for Windows displays
- Language for keyboard installed
¨Printer type - As part of the Windows setup, you are prompted to choose a 
printer. Microsoft® includes the files for many different printers. If you cannot 
find your printer in the list, you will need the floppy disk with the printer driver 
provided by the printer manufacturer. If you do not want to install a printer at 
this time, you can skip this part of the setup. Which operating system to load
¨Operating System Type - During initial setup you must choose which 
operating system to load, either Windows 95 or 
MS-DOS and Windows for 
Workgroups 
(DOS+WFW). This choice is final. You will not be able to change the 
operating system after installation is complete. For most users Windows 95 is 
the better choice. You might want to load 
DOS+WFW under the following 
circumstances.
- Your corporation or workgroup may have guidelines that require use of 
DOS+WFW. Check with your manager to determine the policy at your 
company.
- The software that controls your local area network may not be compatible 
with Windows 95. Check with your network administrator to determine 
whether Windows 95 is compatible.
- Although most software that is compatible with 
DOS+WFW is also 
compatible with Windows 95, it is possible that the existing software you 
are using will not run in Windows 95. If you have a critical software 
application that you intend to copy to your new computer, check with 
the manufacturer of the software to determine whether your application 
is compatible with Windows 95.
