3.4 Boot Processor
The <REFERENCE>(hyperion) system is designed so that all
processors share system resources equally. Because only
one processor can boot the system or use the console at any
given time, this processor is designated the primary or boot
processor. The others are called secondary processors. The
boot processor is selected during the power-up sequence.
