  481. address of the kernel here. The most common setup will have the
  482. processor vectors at the base of RAM and then the start of the
  483. kernel. On some platforms some RAM is reserved for boot loaders
  484. and the kernel starts after that. The 0x400 default was based on
  485. a system with the RAM based at address 0, and leaving enough room
  486. for the theoretical maximum number of 256 vectors.
