If You are advanced Mac OS user You have to know some low level info about all your PCi devices for getting drivers for them
For getting pci id`s in Your system
- download attachement
- unpack it into Applications folder
- make it executable
- open Terminal
- execute command ioreg -c IOPCIDevice > pci_dump.txt
In pci_dump.txt U can see all PCI devices attached in Your hardware
Good Luck!
