Notes: The shaded cells in the table denote unsupported signals.
Signal M66EN is grounded on the motherboard (Ground = 33MHz bus speed).
The KEY pins are to guarantee proper module installation. Pin A1 will be removed
and the female side plugged for 5.0V I/O signals and Pin D30 will be modified in the
same manner for 3.3V I/O. Both pins will be removed for 3.3/5.0 operation.
