Let's see. No DOS, no versions of Windows prior to Vista.
Why? Look up EFI BIOS...
Just realized that all Nvidia cards are now unavailable when you try to configure E1505 computers, and seems like ATI cards are 50 dollars off and also they are the only video cards available, not even Intel GMA is an option.
All this points to one thing. Dell is clearing its stock of ATI cards, and will soon bring the Santa Rosa models. So smart buyers, hold off.
Do you disagree or have other explanations?
