Processors 
The system supports one-, two- and four-processor configurations. In one- or 
two-processor configurations, processors are installed in sockets 1 and 2, and 
FlexMem Bridges are installed in processor sockets 3 and 4 to enable the 
processors to access the adjacent memory set. For more information on 
installing a FlexMem Bridge, see "Installing a FlexMem Bridge" on page 141.
Table 3-5 provides a guide for one-, two-, and four-processor configurations.
