3.2.1 Hard Disk (IDE) Connector (CN4)

A 44-pin header type connector (CN4) is provided to interface with up to two embedded hard disk drives (IDE AT

To enable or disable the hard disk controller, please use the BIOS Setup program, which is explained further in

chapter 5. The following table illustrates the pin assignments of the hard disk drive’s 44-pin connector.
