            Note: Designated pins should be in the closed position.
            W6/pins 1 & 2 and W7/pins 1 & 2 are reserved.

            Note: Primary and secondary IDE drives are enabled by
            selecting a PCI interrupt or attaching the paddle card.
            Primary or secondary IDE drives are disabled by detaching the
            paddle card and disabling the PCI interrupt. To attach the
            paddle card, insert it into an ISA slot and connect PCW1 to
            W1. The paddle card is used to transfer IRQ14 and IRQ15
            signals to the PCI bus on older mainboards that do not have
            this capability.

                       MISCELLANEOUS TECHNICAL NOTES

    Your mainboard and BIOS determine operating modes. If your mainboard
     and BIOS support plug-and-play, the controller can operate in PCI
       native mode. If not, the controller operates in legacy mode.
