 597           Typically on m68k systems the kernel will not start at the base
 598           of RAM, but usually some small offset from it. Define the start
 599           address of the kernel here. The most common setup will have the

 601           kernel. On some platforms some RAM is reserved for boot loaders
 602           and the kernel starts after that. The 0x400 default was based on
 603           a system with the RAM based at address 0, and leaving enough room
