Hey guys. First off, let me tell ytou this is a windows XP problem. I have a Dell Optiplex 450 mhz system which I bought a used 8x DVD drive for. I plugged it in and rebooted. First thing wrong is that there is an error message that says "Secondary Hard disk 1 not found. Press F1 to continue, F2 to run the Setup Util. (BIOS)" So I say, okay, and press F1. Turns out both my hard rives are in full working order. But My DVD drive still isn't recognized. So I looked for drivers on the web, and found one, but it was a DOS drivers and it didn't work. Now I'm in a pickle. Please help me. All I know about the drive is that it is by Raite Optoelectronics. Oh, and one parting word. It says on the back "ATAPI" but it seemed to have an IDE connector.
