shumi,
Since the Wallstreet does no have built-in FireWire ports, no FireWire drivers are installed.
If you go to the Apple menu (upper left corner) > Control Panels > Extensions Manager, then go down the list in Extensions, you probably will not see these three extensions:
FireWire CardBus Enabler
FireWire Enabler
FireWire Support
If perchance they are present but unchecked, check the boxes and then restart.
If they are missing, there are several options for acquiring these extensions.
1. Download the MacOS 9.2.2 Update and run it on top of your already-installed 9.2.2; with the FireWire PC card in the card slot, the installer will see the FireWire hardware and install the FW Enabler and FW Support but not the necessary FW CardBus Enabler because it is not in the Update.

2. Download the FireWire CardBus Enabler file here; you should have as part of your software Stuffit Expander to expand the downloaded .sit file...it will probably expand automatically.

3. Once the downloaded Enabler file is on the desktop, open your HD icon where you will see a folder called System Folder...just drag the Enabler file on top of the System Folder icon and it will automatically be properly placed. I just downloaded this file and it has only a generic icon (plain piece of paper with folded corner) but the file still works fine. I will have to work on generating the custom icon.
4. If you have already run the 9.2.2 Update, you should now have all three extensions; restart and test.
If your Wallstreet is like mine, you must place the FireWire PC card in the 'book and perform a restart (or cold start); otherwise the FW PC card will not be recognized...the card itself is not hot-swappable under 9.x.
P.S. Please use lower-case letters; upper-case is harder to read and is considered shouting.
