You'll need to get a firewire PCI card such as these....

They're cheap and easy to install.

That's great, thanks for your help.

If your Dell came with a SoundBlasterAudigy card, that card has a firewire port built in. If not,when you buy the firewire card, check the ports on it to see whether your cable will work--there are 4 pin and 6 pin firewire ports and the cables can be 4 pin to 6 pin, 4 to 4, etc. I'm not using this but I think the most common is a 4/6--4 pin end to the camera and 6 pin to the computer firewire port.
