Attention! Pins 63-94 only exist for 64 bit PCI applications. KEYWAY1
exists for universal and 3.3V mainboards. For 5V mainboards this pin is GND.
KEYWAY2 exists for universal and 5V mainboards. For 3,3V
mainboards this pin is GND.
+Vi/o is 3.3V for 3.3V mainboards, 5V on 5V mainboards, and defines
the signals for universal boards.
