I have XP pro and 98 on my desktop and XP pro on all of my laptops. I need 98 because i use a program that only supports 98
How do you have 3 OS on one computer(desktop) I am not 100% sure but i think you cant have more then 2
You can even Quad boot http://www.linuxquestions.org/linux/answers/Applications_GUI_Multimedia/Tribooting_a_Computer
Wow, I can't believe I was the only one to vote Linux! I use both XP Home and Linux, but I prefer Linux by a huge margin.
