Expansion slot utility

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)

macpro 2.66, Mac OS X (10.4.8), Sonnet tango express PCIe card

"The Configuration Expansion Slot Utility is located on your Mac Pro at: /System/Library/CoreServices/"

The new Mac Pro (January 2008) has fixed PCI-Express configuration, so does not use it.

The Tango Express cards only needs a x1 slot, so should work in any PCI-Express configuration.

Under Tiger, it should launch IF it sees a card added that is not running at proper speed. Under Leopard, on 2006-era, it doesn't launch, even when it should.

Sounds like the Tango though has a problem of its own.

Malcolm,

You said, "The new Mac Pro (January 2008) has fixed PCI-Express configuration, so does not use it."
So then how or what do we use to configured it with now?

Thanks!
Marc

In the Mac Pro (January 2008), the first two slots are PCI-Express 2.0 x16, the other two slots are x4. The configuration can not be changed, so there is no need for a configuration utility. It is still in Leopard for use with the older Mac Pro.
