689 hex "Address of the base of kernel code"
690 default "0x400"
691 help
692 Typically on m68k systems the kernel will not start at the base
693 of RAM, but usually some small offset from it. Define the start
694 address of the kernel here. The most common setup will have the
695 processor vectors at the base of RAM and then the start of the
696 kernel. On some platforms some RAM is reserved for boot loaders
697 and the kernel starts after that. The 0x400 default was based on
698 a system with the RAM based at address 0, and leaving enough room
699 for the theoretical maximum number of 256 vectors.
