sn25p firewire ports not working

[dozer]

i have a new sn25p and for some reson the firewire ports are not working. they are installed in xpsp2, ive removed and reinstalled the drivers but the device (ext hdd) doesnt register, yet works fine on usb2.

i cant find any bios setting to turn off and on the firewire ports, any ideas?

theres no problem in device manager and ive tried both front and back ports to no avail.

not happy as all my external drives run off firewire, anyone know if there really is a mobo jumper before i rip the thing apart?
