English
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
The advanced Pentium Pro processor installed in your PC provides the
best performance when used with 32-bit operating systems and
applications.
When is a Second
Processor Used?
To be able to make use of a second processor, your PC must be running

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
