CONNECTION THE MOTHERBOARD
Once the mainboard have been fastened into the system case, the next step
is to install the audio extension card and to connect the internal cables.
The internal cables are wire leads with plastic female connectors that attach

and are the points of contact between the mainboard and other parts of the
computer.
A description of each connector and its connector pins follows. See Fig.
3a for the location of the connectors on the mainboard.
Note:
Before making connectors on the board, make sure that power
to the system is turned off.
