When running in TBI mode, the hardware doesn't need to know the number
of cylinders - but it does need to be set to TBI mode.  Pin 56 does
that.  It has four possible values: 4 cyl, 6 cyl, 8 cyl, and TBI.

Once the hardware is set to TBI mode, you still have to make sure the
software is told the number of cylinders (possibly through an EPROM location).
