I have two G4 desktops. The one with the swing arm. One has 256MB of memory and the other has 512MB of memory. I would like to remove the 512 and install it in the G4 that currently has the 256. I am not a huge computer guy so my question is if I do this do I lose my OS. The G4 that I want to install the 512 in has OSX 10.4.11 The other has OSX 10.3.9. These computers don't have a lot that can't be replaced. I can reinstall ilife and office. My main concern is that I don't change the OS. I'm not sure if the OS is on the HD of Memory. Basically when finished I want the G4 that I install the 512 to have OSX 10.4.11. Would be thankful if someone could help me out here.
