 576           Typically on m68k systems the kernel will not start at the base
 577           of RAM, but usually some small offset from it. Define the start
 578           address of the kernel here. The most common setup will have the
 579           processor vectors at the base of RAM and then the start of the
 580           kernel. On some platforms some RAM is reserved for boot loaders
 581           and the kernel starts after that. The 0x400 default was based on
 582           a system with the RAM based at address 0, and leaving enough room
 583           for the theoretical maximum number of 256 vectors.
