Breaking Down The SRC: This table defines the fields of the SRC and their
corresponding Control Panel function. Word 7 of the SRC allows you to determine
the correct 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 busses are determined
by using the DSA and the appropriate system unit or expansion tower card
position table. See “Card Position Tables” on page 282.
