D57 The TYPE pins indicate to the Carrier Board the Pin-out Type that is implemented on
the module. The pins are tied on the module to either ground (GND) or are no-
connects (NC). For Pinout Type 1, these pins are don’t care (X).

NC GND GND Pinout Type 5 (no IDE, no PCI)
GND NC NC Pinout Type 6 (no IDE, no PCI)
The Carrier Board should implement combinatorial logic that monitors the module
TYPE pins and keeps power off (e.g deactivates the ATX_ON signal for an ATX power
supply) if an incompatible module pin-out type is detected. The Carrier Board logic
may also implement a fault indicator such as an LED.
