Noooo, since you're installing another version of Mandrake, you'd just do it during Mandrake Setup using the DiskDrake partitioning utility. (You know, the graphical doohickey with the bars you click on)

Keep clicking arrows until you get to the partitioning section to get a look at the DiskDrake partitioning utility.
