Upgrade to Windows XP

This section describes how to upgrade to Windows XP from Microsoft Windows 98, Microsoft Windows Millennium Edition (Me), and Microsoft Windows 2000 Professional.

Note Before you start the upgrade process, obtain and install the latest BIOS upgrade for your computer from the computer's manufacturer. If you update the BIOS after you upgrade the computer, you may have to reinstall Windows XP to take advantage of features such as Advanced Configuration and Power Interface (ACPI) support in the BIOS. Update the firmware in all of your hardware devices before you start the upgrade if you can.

Also, you may want to disconnect from the Internet during the installation. Disconnecting from the Internet during the installation helps protect you from malicious users. You may also want to enable the Microsoft Internet Explorer firewall. For more information, see the "Enable or disable Internet Connection Firewall" topic in Windows XP Help.
