The update had two seperate flashers so I could have used either (I picked the non-A/V). I flashed in on my Gigabit Ethernet as I needed to boot into an OS to run the updater. I guess I could have put it on a USB stick and ran it on the G3 from the iMac OS9 boot cd that I've been using but I don't know if that would have made any difference. As I said, if OSXS doesn't like it, then it's no use to me.
