CompactFlash Adapter (J23)

The board contains a Type II PC card socket, which allows for the insertion of a CompactFlash Card.
The CompactFlash Card acts as a standard IDE Drive and is connected to the primary IDE bus. If a
CompactFlash card is installed, only one additional IDE drive may be added to the primary bus.
Jumpers are used to select the Master/Slave mode and the voltage selection (+5V or +3.3V). Refer to
Table 2-4, Jumper Settings for more information.
