Win 2k and win NT 4.0 workstation

hello all: I read an article here in Tech Republic about having win2k and win nt 4.0 workstation on the same computer, enabling double booting. Since I read the article a long time ago, is there any way I could find the article again, or anyplace I could read information or how to for achieving this. Do I have to take special care when doing this or is just like installing win98 and win2k on different partitions of my hard drive?
Thanks in advance, Lizet
