You still didn't explain why you need whatever is on that CD. Did you reinstall of XP SP3?  You do know XP hasn't been supported for eons and is full of bugs and unfixed security holes, so not safe to use on the internet, right? Dell actually still offers some drivers, software, diagnostics, and utilities for the D3000 on its Support page, but not everything you mentioned is listed. It's all 10+ years old, but maybe you can find whatever you need there. I tested one file and it downloaded here, so they may all be accessible. No idea if the D2400 uses similar/compatible software...
I lost.my the Cd that came with the computer.  It is a Dell Tools System software Cd for a dell Dimension 3000 That I bought in July 2006. I need help finding a replacement. I see so many on ebay. but would not know what P/N To Pick or what year either.  I have a old xps  8300 tools system software cd but I do not know if that is usable. The 3000 computer is not listed if that matters. Would any know where I can a correct replacement?
