Hi, I want to take my (only) Hard drive in my Pentium 2 and put it in my P3, same with the RAM. HD, RAM and OS (98SE) are perfectly compatible . I want to make ONE computer with these two. My questions : can I simply put the first one into the P3 without erase it or partition it ? I would, of course, set the jumpers behind both HD (master-slave) correctly. At the beginning of the cable or at the middle ? (I read that it wasn't important but I'm not sure). If I run a program on the slave, will it read the registry on the slave or the master ? Do my system will rename the old HD or change his letter ? (from C: to Fr G:...) What about the references in the registry ? Tell me your experiences about it .... Please pardon my english... Thank you !
