Goto dell.com and collect the drivers then make a CD with them.
Or you could find it on Ebay.
I got a Dell Dimension L500r that came with no documentation, HDD, or, unfortunately, Dell ResourceCD. I need to find only the ResourceCD (I have an HDD and found docs online) and am running Windows 98 First Edition as an OS placeholder until I find the way to get this resourceCD with new drivers and Windows 98 SE, and can I get it for free, if at all? This sucks.
