 518           running more threads on a system and also reduces the pressure

 553           Typically on m68k systems the kernel will not start at the base
 554           of RAM, but usually some small offset from it. Define the start
 555           address of the kernel here. The most common setup will have the
 556           processor vectors at the base of RAM and then the start of the
 557           kernel. On some platforms some RAM is reserved for boot loaders
 558           and the kernel starts after that. The 0x400 default was based on
 559           a system with the RAM based at address 0, and leaving enough room
 560           for the theoretical maximum number of 256 vectors.
