;Summary: This program will attempt to scan the PCI Bus
|

; and display basic information about each device
|

; connected to the PCI Bus.

|

;HISTORY:
|
||||
;keep dates in european format (dd/mm/yyyy), please
|
||||
; '!' means big changes
|
||||
;
|
||||
;to-do:
|
||||
; more vendors
|
||||
; vendor's website
|
||||
; 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
