In principle RedBoot is similar to a PC-BIOS and may replace it. But
think about all the hardware initialization stuff a PC-BIOS has to do
after power-up. Most mainboard chip-sets have hundreds of registers
which have to be initialized appropiately, this is no fun. Also you may
have problems to get the documentation of your chip-set(s).
