Thanks for helping me out guys!!! I have an older Compaq Presario that currently has Win98 on it. The machine is 500Mhz fast with about 95 RAM (or a little more). I want to change the OS to Win 2000, but i only have a reinstallation disk with Win 2000 for a Dell Optiplex GX240. I know that with this reinstallation disk, i can completely reinstall Win2K on this GX240 as it was originally done at the factory. Can i somehow use this reinstallation disk to reinstall Win2K on my Compaq? I imagine i would need to reload Dell BIOS on the Compaq? Is this a doable task at all? Thanks a lot!!!
