424 Typically on m68k systems the kernel will not start at the base
425 of RAM, but usually some small offset from it. Define the start
426 address of the kernel here. The most common setup will have the
427 processor vectors at the base of RAM and then the start of the
428 kernel. On some platforms some RAM is reserved for boot loaders
429 and the kernel starts after that. The 0x400 default was based on
430 a system with the RAM based at address 0, and leaving enough room
431 for the theoretical maximum number of 256 vectors.
