Dual Boot: Win2K Pro w/ Win98SE

I need to know how to dual boot my Win2KPro machine with Win98SE. I am a recording musician who has a ProTools rig that will only run on 98SE…but I am also studying for my MCSE and have to keep Win2K on the machine for study purposes (it is current OS ). My machine is a 1G Pentium with 2 20G HDs and U2W SCSI. I need an answer very fast, as my band needs to lay some tracks!! Any help would be awesome.
Thanks.
