  471. Typically on m68k systems the kernel will not start at the base
  472. of RAM, but usually some small offset from it. Define the start
  473. address of the kernel here. The most common setup will have the
  474. processor vectors at the base of RAM and then the start of the
  475. kernel. On some platforms some RAM is reserved for boot loaders
  476. and the kernel starts after that. The 0x400 default was based on
  477. a system with the RAM based at address 0, and leaving enough room
  478. for the theoretical maximum number of 256 vectors.
