If you are trying to get this card to work under Windows XP you Have found the right place. I too had trouble but finally succeeded. I hope that these instructions will help. If you want technical info about the VIA 6306 fire wire card Click Here to get the manual 

Note You must have PCI 2.2 on your motherboard, not PCI 2.1 or lower.
1. Click Here to download required file.
2. Turn off computer.
3. Remove Firewire Card from computer.
4. Turn computer back on.
5. Extract files from downloaded zip file to a temp location.
6. At temp location find file 1394.zip and extract it to CWindowsSystem32 (assuming standard windows installation)
7. Extract 1394.zip to second temp location.
8. At second temp location right click on all .inf files and select install.
9. Turn off computer.
10. Put firewire card back into computer (into a different PCI slot if you can)

Your PCI slot may be bad or the card may be bad. Who knows. Try going to the VIA Support Forums. or here http://www.nthelp.com/NT6/data_is_invalid.htm
