;***************************************************************
;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

;----------------------------------------------------------------
;2.1: PCIDEV   ??/04/2007
;Author:    Mihailov Ilia aka Ghost <ghost.nsk@gmail.com>
;Features:
;           fixed
;                 * Same little bugs
;                 * Source code formating
;                 * PCI version normalized 0210 -> 2.10
;           added
;                 * + 13 vendor (total now 1000!)
;                 * + 3 class type
;                 * Fast call source ready
;                 * Device IRQ detection
;           optimized
;                 * ! size optimized (61025 -> 32501 see added)
;                 * easy to add new vendor & class names
;----------------------------------------------------------------
;2.0: PCIDEV   30/08/2006
;(it differs a lot from the version 1.0, which was introduced 19 months ago)

;           Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Features:
;           added
;                 * Detection of Interface by Mario79
;                 * 122 vendor id's by Wildwest
;                 * Description is based on Class, SubClass and Interface now (PCI 3.0) by Wildwest
;----------------------------------------------------------------
;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.
