Raw Blame History

;***************************************************************
; project name: PCI Device Enumeration
; target platform: MenuetOS, x86 (IA-32), x86-64 achitectures
; compiler: flat assmebler 1.60
; version: 1.25
; last update: 2th October 2005
; maintained by: Sergey Kuzmin aka Wildwest
; e-mail: kuzmin_serg@list.ru
; project site: http://coolthemes.narod.ru/pcidev.html
;***************************************************************
;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:
;PCI version should be normalized (0210->02.10)
;----------------------------------------------------------------
;1.25: PCIDEV 02/10/2005
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Features: !Description is based on Class and SubClass now (PCI 3.0)
; deleted label Descriptions (names of Classes)
; names of Classes and SubClasses are in the end of Vendors.inc
;----------------------------------------------------------------
;1.20: PCIDEV 16/08/2005
;Author: Victor Alberto Gil Hanla a.k.a. vhanla <vhanla@gmail.com>
;Features: !added many vendor lists (865)
; previous version's list deleted
; previous Company Name searching and printing changed
;NOTE:
; It was only tested in my old PII Computer,
; there might be some bugs... PLZ test it and send comments
;----------------------------------------------------------------
;1.15: PCIDEV 03/06/2005
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Features: added quantity of devices,
; ! detection of Company Name based on Vendor ID,
; database of VenID (35 ID's),
; macros.inc for smaller size,
; interface+(skinned window),
; VenID before DevID in 'table'(was DevID before VenID)
;----------------------------------------------------------------
;1.0: PCIDEV 30/01/2005
;Author: Jason Delozier
;Features: able to detect PCI version, quantity of PCI buses,
; Vendor&Device ID for appropriate Device on Bus;
; detect Revision, Class and Subclass of Device,
; and make Description based on Class
