Hi,

Some one can guide me throw the steps? because i really dont know how.
For example must idoenload all 3 cd'd or can i download some upgrade package, because i already have 3 cd's of 9.0 version

Tnx

When u boot up the first cd of Mandrake it should give u the choice to upgrade, do that and continue. I had experience with mandrake 9.2, but never liked it enought to upgrade. Im sure it has and option to upgrade.
