387 Typically on m68k systems the kernel will not start at the base
388 of RAM, but usually some small offset from it. Define the start
389 address of the kernel here. The most common setup will have the
390 processor vectors at the base of RAM and then the start of the
391 kernel. On some platforms some RAM is reserved for boot loaders
392 and the kernel starts after that. The 0x400 default was based on
393 a system with the RAM based at address 0, and leaving enough room
394 for the theoretical maximum number of 256 vectors.
