S video out drivers for dell latitude cpi-r series

I think i might need a driver for the video out slot to my dell latitude laptop. It's the CPI-R model, i believe it has a 400mhz pentium processor It has windows xp professional on it and a 60 gig hard drive. It lost its monitor long ago and i'm hoping to use the svideo to composite cable i have. I tried using it as it is now though and it doesn't work. but i also tried the cable on my other laptop and it works fine that way. to make sure the cable wasn't the problem.

any help would be greatly appreciated. i tride looking for some kind of driver from dell but they only have driver support from windows 2000 down for this model.
