If you have a computer running a Windows operating system that you want to upgrade, you can use the installation disc for the new operating system to run the upgrade process. During the upgrade, you can choose to change the Hardware Abstraction Layer, or HAL, which determines how your computer boots and configures programs. For example, you can move from using an Advanced Configuration and Power Interface (or ACPI) Basic Input/Output System (or BIOS) to an MPS Multiprocessor PC.
Instructions
1. Insert the Windows operating disk for your system or an upgrade of the operating system into the CD-ROM. The installation window will appear.
2. Click the "Install now" option, and select the "Next" option.
3. Enter your product key into the text boxes, and click the "Next" button.
4. Click the box next to the "I accept the license terms," and click the "Next" button again.
5. Click the "Upgrade" option, and the upgrade process will begin.
6. Press the "F5" key.
7. Select the "*halapic.dll" file option for an MPS Multiprocessor PC, and complete the system upgrade.
