1. Because the cpuModule has an onboard +3.3V supply, an external +3.3V supply is not required.
However, if a +3.3 V supply is installed in the system to power PC/104- Plus or PCI-104 expansion
boards, it will be monitored by the CPU at power up.

2. The 12V and -12V rails are not used by the cpuModule. They are only connected between the
bus connector and the power connector. Any requirements on these signals are driven by other
components in the system.

3. 5V Standby is used to power the board when the main supply is turned off (power down modes
S3-S5). It is not required for board operation.
