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