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

# Relocating `boot' at 0x388000 seems to provide a working compromise
