I bet when you boot there is a lot of stuff scrolling up the screen. Those are services that run in the background. Find out which ones you don't need and disable them. That will speed you up a bit.
Which ones you disable will depend on what hardware you have and use.
Maybe someone can tell you which ones to disable. You can see what is running by going to Control Center, like start in windoze, then Configuration then Mandrake Control Center. Click on System then DrakX services. You can click on 'info' for some info. Never cleared up the mud for me though.
Still waiting on 9.2 myself.
