Information resources
The Quick Reference that comes with your computer provides information for installing your computer and starting the operating system. It also includes basic troubleshooting information, software recovery procedures, help and service information, and warranty information.
Access IBM, on your desktop, provides a link to more information about your computer.
If you have Internet access, the most up-to-date manuals for your computer are available from the World Wide Web. To access this information, point your browser to
http://www.ibm.com/pc/support
Type your machine type and model number in the Quick Path field, and click Go.
Tools required
To install some options in your computer, you might need a flat-blade or Phillips screwdriver. Additional tools might be needed for certain options. See the instructions that come with the option.
Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer components and options.
When you add an option, do not open the static-protective package containing the option until you are instructed to do so.
When you handle options and other computer components, take these precautions to avoid static electricity damage:
vLimit your movement. Movement can cause static electricity to build up around you.
vAlways handle components carefully. Handle adapters and memory modules by the edges. Never touch any exposed circuitry.
vPrevent others from touching components.

vWhen you install a new option, touch the static-protective package containing the option to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body.
vWhen possible, remove the option and install it directly in the computer without setting the option down. When this is not possible, place the static-protective package that the option came in on a smooth, level surface and place the option on it.
vDo not place the option on the computer cover or other metal surface.
