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.
