You will need to get a minmal operating system on the hard drive to install the cdrom drivers. If you have already formatted, I am guessing that you have at least got to the point where you have a c:\ prompt on the screen. If you don't, boot with the a: disk that you formatted with. After you get the a:\ prompt, type "sys c:" (without the quotes). Then get the cdrom driver disk or files from the internet and run the install program to set up your cdrom drive.
