Put a disklabel on that drive in a BSD partition (even a very small one. Define a slice that spans the swap partition. Make sure your kernel config for BSD support swapping on the device. This is documented in the config documentation. If not, you will have to rebuild a kernel to do it. Swap on the slice spanning the partition. On a related topic: I'm not sure if the default vnode pager works like it is supposed to in the current code. When I did this, I neither had the current code, nor was using the vnode pager that came with the code at the time. *IF* it works, then you can, after you have enabled mounting of your DOS partition, use your Windows swap file as a swap area. To prevent Windows bitching after you are done running BSD and want to reload Windows (for some unholy reason), you must delete a tag file of some kind. I forget which one. This should be done when/before you start using the Windows swap area. The Linux documentation covers this in detail, so since you have Linux, you can look it up there.
