  Log:
  Assume floppy disk is not inserted when we have exhausted retries.  This
  significantly reduces booting time when there is broken floppy disk drive,
  controller, cable, BIOS, etc.
  When the floppy controller interface is correctly implemented, disk change
  signal (DSKCHG) is reflected in the Digital Input Register (DIR) at 0x3f7.
  However, there are many cases that the signal is unusable.  Moreover, some
  BIOS does not reserve the port at all.  In those cases, the register may not
  function.
