LinuxBIOS is the core piece that initialized the hardware. Then it loads and executable in the ELF file format from the rom. That executable can be the final kernel, or it can currently be one of the following bootloaders: ADLO etherboot. Linux Kernel with LOBOS/2 kernel monte/Kexec support FILO 9Load OpenBIOS .... It is very simple and flexible. As for the PowerPC I think they are directly loading the kernel. All that is required of the bootloader is that it be able to run on the bare hardware making no firmware calls. Like an OS typically does.
