The instructions that come with the camera mention the windows driver, but there is a driver on the supplied disk that is recommended.
I wonder if the firewire card has an updated driver online somewhere? I'd look for it but the damn thing doesn't even have a company name on the box. All on the front is "PCMCIA 3 Port IEEE-1394 Card Bus 32 bit" and a logo with "FireWire" under it. And reading the back it does say it's Plug and Play.
