    'was working'? The project is alive and well.

    It is much more than just embedded systems. In fact with recent addition
    of legacy bios support we are able to boot other operating systems (BSD,
    Win, etc). Being able to boot Windows provides easy migration patch to
    Linux :-)

    By the way. Yes you can burn the linux kernel into flash (together with
    linuxBIOS) and boot it this way. But given that many motherboards limit
    your flash size to 256KiB you probably want to put the kernel on the
    CompactFlash over ide nevertheless. Interestingly enough if not this size
    limit we might have ended up using Linux Kernel as hardware initalizator
    to some degree.

    In fact we are presenting a paper on LinuxBIOS booting other operating
    systems this summer during Usenix 03.
