This description architecturally classifies the processor/memory subsystems as being either a 66-
MHz slot 1 type or a 100-MHz slot 1 type (correlating to the two system board types).
This chapter includes the following topics:
♦
66-MHz slot 1 processor/memory subsystem [3.2] page 3-2
♦
100-MHz slot 1 processor/memory subsystem [3.3] page 3-9
