I have found an old Dell inspiron laptop lying around. it is inspiron 5100 that has a P4 2.40GHZ CPU and I believe 512MB PC2100 ram, :S and a 32MB ati radeon 7500 gfx card. Do i need to install another 512MB stick ? and I read around, that my card can support it, but no aero feature, which i don't mind really. Can win 7 run on it? The latest build, 7600 13865?! And what does the Orbit's win 7 1.8 toolkit actually do? Does it make it RC and then activate or rearm?! or actually activate it?! Thanks.
