If one microprocessor is installed:
–
The microprocessor is installed in microprocessor socket 1 (U82).
–
The microprocessor supports both the startup and application processes.
v
If you install a second microprocessor in the server:
–
The server operates as a symmetric multiprocessing (SMP) server. With an
SMP, operating system 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.
–
Microprocessor 1 is installed in microprocessor socket 1 (U82);
microprocessor 2 is installed in socket 2 (U121).
Notes:
1.
Read the documentation that comes with the microprocessor to determine if you
need to update the basic input/output system (BIOS) code. The most current
level of BIOS code for the server is available through the World Wide Web at
2.
To use SMP, obtain an SMP-capable operating system (optional). For a list of
supported operating systems, go to http://www.ibm.com/pc/us/compat/ on the
