Look at reading the man page(s) for urpmi there you will find your answer...however be aware that KDE 3.2 is not considered "stable" at this point, although other than sound problems I have not had a problem with other utils. There used to be a website
http://www.easyurpmi.org/easyurpmi/index.php..it appears this site is no longer available to have it generate the addmedia command with path to mirror that made it easy to add cooker(the development tree) for mandrake...if you don't understand my post then I suggest you read up on urpmi and take it from there...and consider using main and contrib in the stable 9.2 tree for upgrades, or installations...
