I have lists of systems that can run 10.3 and above, but I can't seem to find my notes on what systems can run 10.1, 10.1, and to a degree, 10.2. I was trying to load 10.1 onto an 800MHz Titanium, and it repeatedly refused, so I am guessing that 10.1 can't handle the Open Firmware version on the later (DVI) Titanium models. Does anyone have the old reference sheets on what models are compatible with specific releases? Before you ask, no, I do not mean for 10.1 to be a primary OS on this system. I am working on a Netboot and NetInstall library, and was using the Titanium to test a NetInstall.
