Cornelius + others. Happy to report a successful but somewhat "nightmarish" (took 5 hours) install of Panther 10.3. I installed OS 9.0.4 as what I thought was a clean install but somehow all my Jaguar stuff was still there. OS 9 was not going to let me eject the installation cd, so I took a pin to get it out. Now with access to the OS 9 desktop, I set about to install 9.1 then the 4.1.9 firmware. OS 9 was not seeing my flash drive with the updates on it so I got online with my dsl modem using Internet Explorer, got the updates that way, installed them from my desktop, even the firmware went perfectly. Then I began the Panther 10.3 "erase + install" process with disk #1, which went great for the first 40 per cent, then without notice, the installer ejected disk #1 without explanation or further instruction so I began the Panther install again. This time the disk #1 install went perfectly, asking me to install disk #2, but ejecting same disk immediately. I just stuck it in again, this time it works perfectly. Disc #3 went perfectly (my custom install was BSD, the iApps, X11), then came about 17 updates, I was set to go. Now I am installing Firefox with about 20 great extensions + my Logitech Click usb mouse which is far superior to the Mac Pro Mouse which came with the computer, then some other software, system configuring. Well worth the effort, am very happy with the result. Thanks again for all your help, without which I might still be using Jaguar.
