Are you sure your device has an PCI / ISA interface. That means it is a stand-alone board that plugs into a pci slot. I'd tend to believe that it's integrated on the motherboard and not a plug in card. If I'm right then you don't need any driver since it's provided by the OS.
For instance I have an Intel mb. in a Dell Dimension 9100 computer that runs automatically after proper detection has occured. In Device Manager I have the following under "IDE ATA/ATAPI controllers"
Intel(R) 82801 GB Ultra ATA Storage Cointrollers - 27DF
Intel(R) 82801 GR/GH /SATA AHCI Controllers
Primary IDE Channel
I did not have to install these drivers.... the system did when the OS was installed. I have a SATA controller and not an IDE interface. It's integrated on my mb.
