141.15Spk# The relocation address for `boot' must leave enough free memory below
151.15Spk# it to load a kernel at address 0x4000. On the other hand, on some
161.15Spk# machines, the PROM uses memory in the upper portion of the first 4MB
171.15Spk# segment, depending on the actual memory bank configuration probably.
181.15Spk# Our boot program must stear clear of that as well.
