Slot Numbering
Physical Slot ID
An operator who wishes to prepare a slot for card removal or insertion must specify the Physical Slot ID. The physical slot number is designated by the system designer and this assignment must be communicated to the Root or Switch port. This is required because hardware must initialize the Physical Slot ID status bit within the Slot Status Register. When configuration accesses are made to read the physical slot ID software makes an association between the Logical Slot ID (Bus# and Device #) and physical Slot ID.
