Diehard, I did actually include both versions of drive setup on the Mac mini CD (1.9.2 and 2.1), the one that opens when you startup is 2.1, but 1.9.2 is found in:
Mac mini OS 9 CD:Applications:Drive Setup 1.9.2
And that is cool, with 1.9.2, I can initialise FW disks from the Mac mini.
Although, the version of drive setup on my Titanium PowerBook is v2.1, and that can format FW drives, but only on the ti and not the mini. (don't have any other os 9 machines to test)
But for now then if you need to restore the Mac mini System onto a FW disk, from the Mac mini, you need to use Drive Setup 1.9.2 in the Applications folder in the CD to do it, to initialise it.
