Use Word 7 of the reference code to determine the bus number, bus type, multi-adapter bridge number, multi-adapter bridge function number, and logical card number from the direct select address (DSA).
Physical card slot labels and card positions for PCI buses are determined by using the DSA and the appropriate system unit or I/O unit card positions. See Card positions for details.
