;***************************************************************
; project name: PCI Device Enumeration
; target platform: KolibriOS and MenuetOS
; compiler: flat assmebler 1.63.2
; version: 1.31
; last update: 13(th) May 2006
; maintained by: Jason Delozier (cordata51)
; e-mail: cordata51@hotmail.com
; project site: http://www.asmfreaks.com/menuetos
;***************************************************************
;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)
;----------------------------------------------------------------
;1.31: PCIDEV 13/05/2006
;Author: Jason Delozier <cordata51@hotmail.com>
;Features:
; fixed
; * ! bug in Company Name look up code that would cause Unknown Name errors.
; * ! possible bugs, many instructions missing byte, word, dword prefixes
; * ! possible bug which could have occured after removing "PREVIOUSVERSIONLIST"
; entry in loop up code and not fixing jump parameters.
; added
; * comments to various parts of the code
; optimized
; * various parts of the source, too many to remember and mention.
; * changed entries for Subclasses in vendors.inc to Byte format, saves a little space.
;----------------------------------------------------------------
;1.30: PCIDEV 11/05/2006
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Features:
; added
; * 3 new vendor id's (ESS from Madis Kalme and 2 id's
; forgotten from 1.15 release: Broadcom -SiByte and Chaintech Comp.)
; changed
; * I don't know why other devs (Jason or Victor) changed window style
; to old ugly one, so I changed it back to skinned type 3.
; * the same goes to the use of macroc.inc - it is enabled again.
; deleted
; * there is no more label "PREVIOUSVERSIONLIST" - id's moved to the
; appropriate parts of global list.
;----------------------------------------------------------------
;1.29: PCIDEV 30/04/2006
;Author: Jason Delozier <cordata51@hotmail.com>
;Features:
; fixed
; * ! bug that would not allow devices with device
; numbers > 16 to be displayed.
; added
; * ! another heading called "FNC" (function) which allows
; the multipurpose Device/Function varible to be split and
; displayed to the user properly.
; * horizontal bars to display for easier reading.
; optimized
; * vendor/description search routines for speed and space.
;----------------------------------------------------------------
;1.25: PCIDEV 02/10/2005
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Features:
; changed
; * ! Description is based on Class and SubClass
; now (PCI 3.0). The Names of Classes and SubClasses
; are in the end of Vendors.inc
; deleted
; * label "Descriptions" (names of Classes)
;
;----------------------------------------------------------------
;1.20: PCIDEV 16/08/2005
;Author: Victor Alberto Gil Hanla a.k.a. vhanla <vhanla@gmail.com>
;Features:
; added
; * ! many vendor lists (865)
; deleted
; * previous version's list
; changed
; * previous Company Name searching and printing
;----------------------------------------------------------------
;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,
; changed
; * 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
