I'm restoring a 12 powerbook I got as a hand me down. I've been researching a ram upgrade, and officially it says it supports 640 mb, with only one ram slot. but i have been reading around that, I can stick a 1 GB stick in there and get it to recognize it. What i want to know is, do i have to do anything special to do that? Or will it automatically recognize it if I stick it in there? This the original 867 model.
