INTEGRATOR’S NOTES

• Use only ATX12V-, SFX12V-, or TFX12V-compliant power supplies with this board.

ATX12V, SFX12V, and TFX12V power supplies have an additional power lead that

provides required supplemental power for the processor. Always connect the 20-pin and

4-pin leads of ATX12V, SFX12V, and TFX12V power supplies to the corresponding

connectors on the Desktop Board, otherwise the Desktop Board will not boot.

• Do not use a standard ATX power supply. The Desktop Board will not boot with a

standard ATX power supply.
