[LAU] Dell 1394 4 pin connector

[Kim Cascone]

I have a Dell Studio 1537 which has a 4 pin 1394 connector

I checked to see if my Ubuntu 10.10 upgrade would allow my Presonus 
Firebox to work

which it allegedly does:

but my system didn't recognize my Firebox after plugging it into my Dell 
using a 4-pin to 6-pin cable

so of course I'm wondering if I need to buy an ExpressCard Firewire 
adapter and if that would work

does anyone have any suggestions or experience with this before I trot 
off to Fry's in search of said adpater?
