installed must be in PCI bus slots.
Notes!
-The second board cannot be properly installed unless the
resources (I/O addresses and interrupt level) for the board can
be allocated. Before attempting to install the second board,
first determine what PC resources are free.
-The resources used for each board do not depend on the location
of the PCI bus slot or the board itself. If you remove two or
more board that have already been installed and then remount
one of them on the computer, it is unknown which one of the sets
of resources previously assigned to the two boards is assigned to
the remounted board. In this case, re-check the resource
