The Vulcan Hard drive switches:

Switch 1: Interrupt Enable
This switch must be closed in order for any interrupts generated by
Hard Drive to pass through to the Apple. (Interrupts are not used at
this time)

Switch 2: PS Enable
When pseudo-slotting in the Apple IIgs, this switch must be closed.
When pseudo-slotting in a II or II+, this switch must be open.

Switch 3: II+ Boot Enable
Leaving this switch open allow a II+ or an unenhanced IIe to boot
directly from the hard disk. If the hard disk is not to be boot device
in these systems, this switch should be closed. In a IIgs or an
enhanced IIe this switch should also be closed.

Switch 4: Pseudo-Slot Enable
When this switch is closed the controller card will show up in slot 7,
no matter which slot it is it. With it open, the card uses the slot in
which it is placed.
