|If it's an on-board port or the card originally came with the computer you'd go to the support page for the motherboard manufacturer or the system manufacturer (HP?). Otherwise, open the case and examine the card for model number or chipset type. Same thing with the 'PCI simple communications controller' (the modem). Not sure what the 'PCI device' is. It's best he download all drivers showing on the support page for his OS.|
If he has no internet connection on another PC then maybe you or someone else can download the necessary files.
