The Quattro-PCI hardware appears in Device Manager in two places:
under the Multi-function Adapters tree and as part of the Ports tree.
Please note that any changes to the Resources (I/O Address & IRQ) used
by any one of the four ports on the Quattro-PCI must be made through
the Resources page of the appropriate Quattro-PCI PARENT – not
through the individual Ports pages.
Modifying I/O Address and IRQ Resources is NOT recommended.
