4.19.3 Installing an Additional Processor

✎
A manual Hardware Abstraction Layer (HAL) upgrade is necessary when
installing a second processor after the system has gone through the software
bundling process. If a second processor is installed prior to unbundling, a
manual upgrade is not necessary.

Hardware Abstraction Layer

To update Windows NT 4.0 or Windows 2000 to recognize a second processor using the
Hardware Abstraction Layer (HAL), complete the following steps:
1. Start Windows.
2. Insert the upgrade diskette. Then select Start > Run.
3. Type A:\setup.exe and select OK.
4. Select Uniprocessor HAL and Kernel.
5. Select Upgrade and insert the media used to upgrade the operating system to a new
Service Pack if requested; then click Retry.
6. If prompted, insert the operating system CD and click OK.
7. After the installation is complete, close the setup program and restart the workstation.

Additional Processor Installation

You can upgrade the workstation to a multiprocessor system. When you install a second
processor, it must be the same speed, cache size, and type as the existing processor.
Ä
CAUTION: Static electricity can damage the electronic components of the workstation.
Before beginning these procedures, be sure that you are discharged of static electricity by
briefly touching a grounded metal object.
1. Prepare the workstation for disassembly (Section 4.2), then place it on its side.
2. Remove the access panel (Section 4.5).
3. Remove the memory expansion board (Section 4.9.2).
4. Disconnect the cables from the hard drive and move them away from the processor area.
5. Remove the main air baffle (Section 4.16.1).
