  463. Typically on m68k systems the kernel will not start at the base
  464. of RAM, but usually some small offset from it. Define the start
  465. address of the kernel here. The most common setup will have the
  466. processor vectors at the base of RAM and then the start of the
  467. kernel. On some platforms some RAM is reserved for boot loaders
  468. and the kernel starts after that. The 0x400 default was based on
  469. a system with the RAM based at address 0, and leaving enough room
  470. for the theoretical maximum number of 256 vectors.
