    You can boot from CF in two ways, IDE compatibility mode or CF/PCMCIA
    mode. In IDE compatability mode, the CF card interface is mapped like an
    IDE disk drive, so your platform needs a true IDE controller. Your
    bootloader will have to load the NK.BIN by looking for the file in a FAT
    based filesystem (if you choose to use FAT). If you are using a CEPC you
    can have the BIOS read the boot sector off the CF card and then perform a
    preboot step to load a second loader (like a DOS loader) that can perhaps
    use low level BIOS commands to get the rest of the NK.BIN. There are some
    3rd party DOS FAT systems you could use to access the NK.BIN (or just
    license MSDOS).

    If your CF card is to be used on a platform with just a CF/PCMCIA
    controller, then your bootloader needs rudimentary card services software
    to access the card in PCMCIA mode. Your bootloader will still have to
    access the card and find the file using whatever file system you decide
    on. Again, if this is a CEPC, there are 3rd party DOS based cardservices
    products that can do the trick of accessing CF cards like disk drives.
    For CEPC, the code to parse nk.bin, load it into extended memory and jump
    to it (switch to big-real mode) can be found in loadcepc(which requires
    MS-DOS). I believe CE.NET now has a standalone BIOS boot from disk.
