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 control to the kernel. The current trend is to include this functionality in the ROMMontior^?, as is the case with ppcboot.

Although some of the data is board specific, you can assemble the bits from information available on the net: http://lists.linuxppc.org/listarcs/linuxppc-embedded/199911/msg00034.html

9.1. bugboot

For PreP^? and PowerPlus^? SBC's, see:

• linuxppc/bugboot-0.3.tar.gz

9.2. mbxboot

The old bootloader included in the kernel source tree, originally written for the MotorolaMBX board, and since ported to a wide range of platforms. This is the start-up component of the zImage that knows how to decompress the kernel. mbxboot is now being rendered obsolete by ppcboot.
