We recently received a new piece of production equipment that included an HP ProDesk 600 G1 WIN7 Home Premium 64-bit PC. The manufacturer assures me that the PC is unchanged for their purpose other than the install of their controller software and a static IP assigned to the onboard NIC which is used to communicate with their equipments controller board.
I'm trying to install a PCI-e x1 NIC into this PC for connection to our network. For some reason the card is not being detected by the WIN7 OS. I've tried all three PCI-e slots on this computer, reset the bios to factory defaults (in case something was changed) and tried multiple cards, all with the same result. I've also checked the cards in other PC's and they are detected normally and I'm prompted to install the driver.
When a cable is plugged into the NIC the indicators on the back show activity but there is nothing showing for the 2nd NIC in Device Manager or Adapters in Network and Sharing Center.
Is there some obscure setting in the bios that I'm not seeing that disables hardware detection? Has anyone ever run into a similar case before?
