How to read PC's I/O (port 80h) port from PCI BUS with Arduino?

[spark2k06]

I would like to make a PCI PCB with a socket to insert an Arduino Nano and communicate through it to PCI BUS and to read codes sent to port 080h I/O PC (Power On Self Test)

I can not find information about it on Internet, anyone know what Arduino/PCI pines and making connections and getting this data?

Sorry with the english!! (I used google translator) you understand?
