config RAMSIZE

config VECTORBASE

	help
	  Define the address of the system vectors. Commonly this is

	  actually setting the address to use.

config KERNELBASE

	  Typically on m68k systems the kernel will not start at the base
	  of RAM, but usually some small offset from it. Define the start
	  address of the kernel here. The most common setup will have the
	  processor vectors at the base of RAM and then the start of the
	  kernel. On some platforms some RAM is reserved for boot loaders
	  and the kernel starts after that. The 0x400 default was based on
