Industry Standard Architecture – Student Guide 2 – Pages 163/164:
Processor compatibility
The new processor must be physically compatible with the processor slot on the system board. A
requirement for multi-processor systems is compatibility of the new processor with the existing
processors.
Operating system update or reconfiguration
On a multi-processor server, the operating system must be capable of handling more than one
processor. If the OS version does not support more than one processor, it must be updated to a
version that does support multiple processors.
BIOS update
It usually is necessary to update the system BIOS to support the increased speed or cache size of
a new processor. Once again, it is necessary to check the documentation provided by the server
manufacturers, who often provide new BIOS versions on their web sites.
