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-Plusor 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.

4.With proper cooling (See Thermal Management on page 65)
