    Unfortunately some BIOSes emulate packet mode, which is why it doesn't
    always work.  Most should get it right these days but I think we still
    need the option to use CHS.  The BIOSes that emulate packet mode take
    the logical sector number, translate it to CHS, and then translate it
    back.  It's that bad.
