Installing a processor
Your xSeries 370 server comes with at least one processor installed on the
standard processor daughterboard. When you install one or more additional
processors, your server can operate as a symmetric multiprocessing (SMP) server.
With SMP, certain operating systems and application programs can distribute the
processing load among the processors. This enhances performance for database
and point-of-sale applications, integrated manufacturing solutions, and other
applications.
Note: To ensure that your operating system supports multiprocessing operations,
Your server supports a maximum of eight Intel Pentium III Xeon processors. For a
list of supported operating systems, see http://www.ibm.com/pc/us/compat/ on the
World Wide Web.

load the appropriate multiprocessor option software in your operating
system programs.
Before you begin:
Thoroughly review the documentation that comes with the processor, so
that you can determine whether you need to update the xSeries 370 server
basic input/output system (BIOS). Verify that you have the latest BIOS level
for your server by accessing http://www.ibm.com/pc/us/compat/ on the
World Wide Web. Refer to the "Getting Help, service and information"
section of the User's Reference on the IBM xSeries Documentation for the
appropriate World Wide Web addresses.
If you plan to use the processor serial-number security feature, you must
change the setting of the Processor Serial Number Access menu choice
in the Advanced Setup menu of the Configuration/Setup Utility program.
The default value is Disabled; change this value to Enabled.
use processors with the same cache size and core frequency as those of the
currently installed processor.
speed, be sure the processor core frequency selection jumper block is set
correctly. (See "Processor-controller board jumpers" on page 34 for more
information. For a list of supported processor speeds, see
http://www.ibm.com/pc/us/support/ on the World Wide Web.)
processor terminator card must be installed in each processor connector. A

processor daughterboard (A).
more than four processors in your server.
install the two cache coherency filter cards in the two adjacent, vertical slots
between the two processor daughterboards on the processor controller board.
