                       MISCELLANEOUS TECHNICAL NOTES

    JP10 is used to configure the card to comply with the PCI IDE Legacy
   convention. Pin 4 of JP10 connects to IRQ14 of the Legacy IRQ card to
  enable IRQ14. Pin 5 of JP10 connects to IRQ15 of the Legacy IRQ Card to
                              enabled IRQ15.
