Input Power
The 40-Pin IDE Flash Module offers 2 ways to get
input power, either via the small power cord or through
Pin 20 of the IDE connector. If Pin 20 of the IDE
connector is defined as NC (No Connect), then the
40-Pin IDE Flash Module must be directly connected
to your system’s power supply. If Pin 20 of the IDE
connector is defined as VCC, then the 40-Pin IDE
Flash Module can get necessary power without use of
the power cord.
