Chapter 5. Installing options 55
Microprocessor
The server comes with one or two microprocessors installed on the system board. If
you have two, or had one and you installed a second microprocessor, the server can
operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating
systems and application programs can distribute the processing load between the
microprocessors. This enhances performance for database and point-of-sale
applications, integrated manufacturing solutions, and other applications.
Notes:
1. Before you install a new microprocessor, review the documentation that comes
with the microprocessor, so that you can determine whether you need to update
the server basic input/output system (BIOS). The latest level of BIOS for the
server is available through the World Wide Web.
2. Obtain an SMP-capable operating system (optional). For a list of supported
operating systems, see http://www.ibm.com/pc/us/compat/ on the World
Wide Web.
3. If the server comes with one microprocessor, it is installed in microprocessor
connector 1. This is the startup (boot) microprocessor. If you install a second
microprocessor in microprocessor connector 2, the two microprocessors will
share the system load after the system has started.
Attention: To avoid damage and ensure proper server operation install
microprocessors that are the same type, and have the same cache size and the same
clock speed. Microprocessor internal clock frequencies and external clock frequencies
must be identical. See the ServerProven list at http://www.ibm.com/pc/compat for
a list of microprocessors for use with the server.
