9. Boot Loader
If you're using custom hardware, or want to replace the ROM monitor on your
board, you'll need a boot loader that knows how to decompress and transfer c
ontrol to the kernel. The current trend is to include this functionality in
the ROM monitor, as is the case with ppcboot.
Some of this is board specific, but you can assemble the bits from what's al
ready available on the net: http://lists.linuxppc.org/listarcs/linuxppc-embe

9.1 bugboot
For PreP and PowerPlus SBC's, see: http://members.home.net/mmporter/linux/ h
ttp://members.home.net/mmporter/linux/linuxppc/preploader.tgz http://members

9.2 mbxboot
The old bootloader included in the kernel source tree, originally written fo
r the Motorola MBX board, and since ported to a wide range of platforms. Thi
s is the start-up component of the zImage that knows how to decompress the k
ernel. It is now being rendered obsolete by ppcboot.
