I found an old computer Pentium 166 MHz I formatted the hard drive but the CD ROM drivers didn't load from the Windows 98 floppy I used. I went on the Internet and downloaded the driver on a floppy disk. How do I get the driver to install? There is no operating system installed on the computer. I can get to the A prompt. What command do I type to install the driver. I typed setup at the A prompt but that didn't work.
