Thanks so much, Allan. You are exactly right. I have been using a G4 AGP with a Sonnet processor and used to have all the necessary updaters, and all my music software and hardware is all G4 era. It's getting on, and I got a chance to pick up another G4 for change, and it turns out it's in pretty good shape. I have another Sonnet processor I want to put in, and couldn't find my firmware updater, and all the google pages had outdated links. I don't use the Apple support pages much, and it's changed so much I couldn't figure out how to find it. I was going to use it for parts, but it is pretty clean so I might completely swap out the one I am using for this one, after getting a new hd and RAM for it. Thanks again, one headache cured! I used to use OS 10.4/OS 9.2.2 and go between both, but I started having a lot of trouble with the screen going nuts one me when switching to OS 9.2.2 from OS 10x, so I completely dumped the idea and just use the G4 2. OS9.2.2 for my music, and now have a Mini for other communications. A lot less stress. Thanks again for finding that page. I bookmarked it and downloaded. Michael
