    OK, looks bad for me.

    Just for my interest:

    Why does a certain IDE controller not support LBA48?

    I always thought an IDE controller isn't more than some ISA-styled bus
    with 3 address lines, 2 chip selects and special stuff for
    DMA-transfers, together with very special timing generators for PIO-modes.

    Whats the problem with these controllers? LBA48, i thought, isn't more
    than writing the LBA-registers twice (because of the FIFO), and using
    different commands for reading/writing (the _EXT functions).
