 ;***************************************************************
 ;Summary: This program will attempt to scan the PCI Bus
 ;        and display basic information about each device
 ;        connected to the PCI Bus.
 ; Subsystem id and Subsystem vendor id detection
 ; Full device detection (like "ATI Radeon 9200") will increase app
 ; size a lot and probably it is function of particular drivers
