Well, there are two ways to install onto the ROMs. One is to just use
the builtin flash disk to store pbsdboot.exe + netbsd. that's easy.
The other is to install new ROMs and write a boot monitor. That's
insanely hard, and individual to each family of products (and maybe
even sub-family)... Not likely worth it as the only real benefit is
reduced power consumption in sleep mode.
