399 Typically on m68k systems the kernel will not start at the base
400 of RAM, but usually some small offset from it. Define the start
401 address of the kernel here. The most common setup will have the
402 processor vectors at the base of RAM and then the start of the
403 kernel. On some platforms some RAM is reserved for boot loaders
404 and the kernel starts after that. The 0x400 default was based on
405 a system with the RAM based at address 0, and leaving enough room
406 for the theoretical maximum number of 256 vectors.
