i.LINK Headers
The system board has two i.LINK headers: 1394HEAD2 and 1394HEAD3.
An internal cable connects the 8-pin header (1394HEAD3) to an interface
unit mounted behind the front of the chassis. The interface unit connects
to the 4-pin i.LINK (IEEE1394) header at the bottom of the front panel.
The other 8-pin header (1394HEAD2) is not used.
