MultiBooting Problems!!!!

I would like to multiboot linux, windows 2000 Pro and WinXp Pro. I currently have win2k and xp multibooted and when I go into fdisk to create the partitions I have to create a primary, secondary, and logical dos drives. I want to be able to have each os on an even amt of disk space, but when I set up my partitions i can only go up to 2024 or so MB of disk space and then the last partition is the rest of my hard drive. does anyone know how to get around this?
