BootBus
The CPU modules support an alternate 8-bit bus (the BootBus) used after a reset to
fetch the first instruction they execute.
The address space of the BootBus corresponds to the boot PROM addressing space
as defined by the Sun4u/Sun5 architecture. The CPU issues its SPARC V9
RED_MODE trap vectors from this address space.
