Second Partition as Virtual Memory?

Here is the situation:

I have a 40 Gig hard drive partitioned as follows: C:\= 31 Gig D:\= 7 Gig (and change) Operating system installed is Windows 98 SE. on C:\ System physical memory is 128 MB SDRAM

Other than setting D:\ as drive for swapfile usage and using settings of 550 MB Min. and 2000 MB Max. do I need to put any system files in the swapfile drive? And if so which ones?
