Firewire bus

[gale]

I purchased a Firewire external device. Bought a card which plugged into a PCI slot. Ran a Belarc diagnostic which showed I had Firewire speed of 400Mhz but the PCI bus runs at 33Mhz.The printout also refers to a Firewire bus~ could someone explain.Thanks.

The PCI-bus speed is an internal clock-speed for data from the mobo-connectors to the CPU and has nothing to do with the Firewire speed.
This is governed by its own hardware onboard the Firewire card.
Don't know about a Firewire bus, sorry.

The firewire speed is between the device and the FW controller. The PCI bus speed is between the FW controller and the CPU/memory.

It is called the FireWire but because you can attach several devices to it. AFAIK FireWire supports up to 63 devices attached.
