promise ata 100 ide controller & XP

Does anyone know where I can download Promise ata 100 drivers for XP?
In fact, everything works fine, I just want to get rid of question mark under device manager.
I also tried updating with 2000 drivers but nothing happened.

I'm not sure about the drivers. I'm actually suprised Win XP didn't install it's own for it. But if the controller card does'nt have any drivers installed or there installed wrong. you pc is most likely running in MS dos compatibility mode, which is MUCH slower then normal mode. Atleast that is what would happen to me when I did'nt install my controller card drivers.
