What OS are you using?

Has it only started displaying the error message recently?

Have you done anything which might have (inadvertently) caused it - i.e. uninstalled a program?

Do you have to install particular software/drivers for your firewire products?

You might get away with doing a System Restore, to a date/time just before you started seeing the error message?

But you may have to reinstall the chipset drivers - since it's those which (primarily) control the USB and firewire ports.

You should have them on a disc you got with the system, but you can get the latest drivers off the XPS 630 'Drivers & Downloads' page.

Be sure to select the appropriate OS/version first though.

Let us know if they help or not?

MANDROMEDAC,
If the message is appearing before Windows starts to load then you'll likely need to open the computer up and reseat the connectors of the firewire (1394) cable.

thanks for reply

the os is vista ultimate 32bit

the error is there before windows loads

i think openning the computer is the right way to go cause ive tried everything else and i heard of a solution like that before something to do with resetting the jumper

i tried reinstalling os with no luck

so i need to know how to reset the jumper or reseat the connectors as surgested

thanks
