To use this board in a non-dell case w/o front USB & sound:
* Jump (connect) pins 10-13 (L) and 12-15 (R) for rear sound.
** Jump (connect) pins 2-14 to avoid Front panel USB cable not detected error.
The Dell Dimension 2400 uses the standard 9 pin USB header for the front ports and use a separate connector for the front headphone jack (the same connector used on many dells of that era).
