SS1 Determines the "drive select" for the 3.5" and 5.25" FDD.
In the default position (A) the *A* drive is the 3.5" FDD
**if** the dual drive is in the upper slot of the pc and
uses the FDD connector on the end of the cable (after the
"twist").
If the SS1 jumper is changed to the (B) position, the 5.25"
FDD becomes the *A* drive **if** the dual drive is in the
upper slot of the PC and uses the FDD Connector on the end
of the cable (after the "twist").
SS2 No jumpers are necessary between the 0-1-2-3 jumpers.
The D-S jumper determines the rotational speed of the
5.25" FDD. The default position (S) sets the speed to 360RPM.
The (D) position sets the speed to 300RPM.
The L-H jumper determines the mode of the 5.25" FDD.
The default position (H) defines Low as Norm mode and
High = High mode.
