Is it possible to install 2 instances of SQL Server 2000/2005 on same PC? If Yes how

My application uses SQL Server 2000/2005 database as back end. It is required to setup multiple environments (development, QA, Pre-Prod etc) on same PC. Is it possible to install two instances of SQL Server in single PC to be referred by different applications installed for different environments? If yes, how to do it?
