Most likely, no, they won't be compatible. In a desktop MAYBE, but laptops are generally very specific.
If you need a firewire port, look for a firewire add-in card. Also take note that Windows doesn't tend to play too nicely with firewire. It may have improved since I last tried with with XP, but back then support for firewire was basically lipservice only.
I was wondering if I am able to swap a motherboard from my HP dv6t laptop (I have a model dv6t-1300) with a motherboard from an HP dv7t laptop. I need to install a new compatible motherboard that has an IEEE firewire port on it. Please help, I am running out of resources.... Thanks in advance!
