Use dell.com and the SERVICE TAG from the machine.
Software such as BELARC ADVISOR and EVEREST are good too but miss documenting the power supply ratings and more.
I've been away from these forums for a while and forgot the names and sites to get the programs that identify the computer internals.
Also can I download as a file to my computer via cable and put on a CD or a keychain drive to install into another computer?
I have a working Dell Dimension 4550 that the business user wants to clean-up by using the Dell CD. Not certain that I will dive into that until I see if some clean-up would be better. Need to research how far back the CD takes one.
Also not sure how to get into the BIOS on a Dell.
Going to hook the Dell up now and then check back for any answers.
The Dell site still has a lot of info on this model.
