HP Vectra XU 6/XXX Optimization Manual page 7

If your PC is running an MPS-ready operating system, installing a second Pentium Pro
processor will yield a significant performance advantage. The second processor works
alongside the first and shares the processing workload. This can increase the overall
processing performance of your PC by up to 80%, depending on your application.
NOTE
When is a Second Processor Used?
To be able to make use of a second processor, your PC must be running an MPS-ready
operating system, such as Windows NT or SCO UNIX. If your PC is not running an MPS-ready
operating system, you will not be able to gain any benefit from installation of a second
processor.
The table below shows which of the more commonly used PC operating systems are MPS-
ready.

Refer to the manual supplied with your operating system for more information on its
characteristics and capabilities.
The advanced Pentium Pro processor installed in
your PC provides the best performance when used
with 32-bit operating systems and applications.
