DX79SI What is the Firewire Chipset used on the Board?

Hi I want to buy the DX79SI motherboard but I need to know the chipset used for the 2 Firewire ports on this board

I do have experience some weird behaviours with some chipser so I just want to make sure the ones installed on this board are compatible with my Audio Card (RME Fireface UFX

Thanks for your help

Regards
