The box simply will not boot to the core 4 CD,yet I have successfully done another core 4 install on a different box. When this box was new I had to install core 3 because of the same problem. Wish I don't have to upgrade, since the box is very happy with core 3. Is there a way of passing the megaraid driver that core 3 uses during the install of core 4?
