I am in the process of upgrading a G3/400 B/W, from 10.2.8 to 10.4.6. Experiencing a couple of issues with this process. Before I started, I installed new Crucial RAM (2) 256 in first two slots and moved the 128MB chips that were there into the last two slots. Under system profiler, it says I only have 128MB in each slot. Strange, I checked Firmware and it said it was up to date. The second issue is the remaining time when installing system seems long, 2hrs. I just did this same thing to five others that were running 10.2.8 and they said time remaining of about 40 mins. Again strange, any thoughts.
