Installing other operating systems

If you install your own operating system, follow the instructions that come with
your operating system CDs or diskettes. Remember to install all device drivers
after you install your operating system. Installation instructions are usually
provided with the device drivers.
The DOS Proof of Entitlement that was included with your computer provides
information required to receive a copy of DOS. Mail the Proof of Entitlement form
to receive your copy of IBM PC DOS. The form requires the following information:
your contact information; computer machine type and model; computer serial
number; copy of purchase receipt.

Updating your antivirus software

If your computer has a preloaded Microsoft Windows operating system, it comes
with antivirus software that you can use to detect and eliminate viruses. Lenovo
provides a full version of antivirus software on your hard disk with a free 90-day
subscription. After 90 days, you must get a new virus definition.
For more information about updating your antivirus software, refer to the Access
Help online help system . See "Access Help" on page 42 for instructions on how to
open the online help system.

Shutting down the computer

When you turn off your computer, always follow the shutdown procedure for your
operating system. This prevents the loss of unsaved data or damage to your
software programs. To shut down the Microsoft Windows operating system, open
the Start menu from the Windows desktop, click Shut Down. Select Shut Down
from the drop down menu and click OK.
