Firewire performace with Windows XP is poor

[tomsvideo]

I am using Windows XP on the Mac Pro but get very poor firewire 400 performance with an external hard drive. I installed a generic firewire card and the drive works great under XP and OSX giving me good performance with the generic card. Anyone else with the same problem with the Apple firewire? What does device manager say the firewire chipset is? Anyone get the Firewire 800 to work on XP? I have upgraded to the new firmware(fixed the sata issue) and bootcamp 1.1.1 but still poor performance.

I read in another forum that it's was a driver issue :/
May be you could search for specific XP drivers for firewire in Intel chips ?

Firewire slow

I have searched google and can not find any other info - can someone look under device manager and see what te firewire controller is named on their machine?

Apparently FireWire is limited to 100Mbp/s under Windows XP, which is 25% of its full capable speed. Do as this link to the Devil says, and let me know if it helps
