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