Nonpageable Memory Location

For Solaris 7 11/99, the location of nonpageable memory (that is, OBP and kernel memory), the kernel cage, resides in the highest physical address space, which generally is on the highest-numbered system board in the domain. The direction of growth of this area is from highest to lowest physical addresses. Exceptions to this rule do exist. Always use drshow(1M) to verify a board's memory state.
