Apple Expansion Slot Utility Download

I installed a tango express PCIe card in my mac pro 2.66. The instructions said that the expansion slot utility would open when I started the computer. Nothing opened, and there is no expansion slot utility in the utilities folder. I'm using 10.4.8. Is this an obsolete utility for this version, or is it located somewhere else. The usb ports seem to work but the firewire ports don't work as I expected. (Only 1 port will work at a time and even one port won't work properly in conjunction with the built in ports. I'm using them with MOTU audio interfaces)
