Another partitionQuery from a newbie

I have Knoppix ver3.1 and I want to know how you install this version on to your hard drive if your hard drive is already partitioned into 4 partitions, 3 as FAT32 partitions and the last as EXT2FS. The first has XP Pro Installed, the second 98SE , the third is use as a protected storage area and the final one is unused. The sizes of the partition are as follows 1)25.007 Gig (XP)
2)10.142Gig (98se)
3)14.982 Gig (Storage)
4)7.106 Gig (EXT2FS)

What changes do I need to do to be able to install Knoppix and still be able to boot into XP & 98SE
