J2 IDE Activity Indicator LED
J2 is a two-pin berg that is attached via a cable to the externally-mounted IDE Activity LED. This LED
lights when the IDE drive is running.
Warning
In some IDE drives, you may have to disable the
IDE LED mounted on the drive by changing a
jumper or setting a switch on the IDE drive itself,
before the IDE drive sends a signal to J2.
J33 Turbo Switch Connector
J33 is a two-pin single-inline berg that is attached via a cable to the externally-mounted bipolar Turbo
switch on the chassis. The turbo switch allows the user to change the motherboard clock speed between high
and low speeds.
