  489. Typically on m68k systems the kernel will not start at the base
  490. of RAM, but usually some small offset from it. Define the start
  491. address of the kernel here. The most common setup will have the
  492. processor vectors at the base of RAM and then the start of the
  493. kernel. On some platforms some RAM is reserved for boot loaders
  494. and the kernel starts after that. The 0x400 default was based on
  495. a system with the RAM based at address 0, and leaving enough room
  496. for the theoretical maximum number of 256 vectors.
