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