As an operating system developer, '''you should not be looking for this'''. There"Standardized" I/O ports are fewonly devices{{which}}used thatin aresome fairlysituations, consistentsuch as hardware that was present on PCpre-PCI based(AT and compatible, etc.) PC hardware. Examples of devices using "standardized" I/O ports are the [[Floppy Disk Controller|floppy drive]], but[[Serial Ports|serial]] and [[Parallel port|parallel]] ports, However, most ports are claimed by plugin cards{{which}} you might not have and some{{which}} are even assigned via PNP which means that any port could be used for the device in question. If you want access to a device, you will need to look up the details for the device in question, and if some fixed port is involved, it will tell you. It is not technically feasible to have a complete mapping of ports to devices as you won't get access to it.
