2. Obtain an SMP-capable operating system (optional).
For a list of supported operating systems, see

Web.
3. The microprocessor that is installed in microprocessor
connector U3 is CPU 1 or processor 1. If a
microprocessor is installed in microprocessor connector
U17, it is CPU 2 or processor 2. If the server has only
one microprocessor installed, that microprocessor is
installed in microprocessor connector U3 and is the
startup (boot) processor. If more than one
microprocessor is installed, the microprocessor with the
lower stepping level is the startup processor and the
microprocessor with the higher stepping level is the
application processor. If both microprocessors have the
same stepping level, the microprocessor installed in
microprocessor connector U3 is the startup processor
and the microprocessor installed in U17 is the
application processor.
Note: You can determine the stepping levels of the
installed microprocessors using the
Configuration/Setup utility program.
Attention: To avoid damage and ensure proper server
operation when you install a new or an
additional microprocessor, use microprocessors
that have the same cache size and type, and
the same clock speed. Microprocessor internal
and external clock frequencies must be
identical.
