I am running FreeBSD 2.0 with two disks:
   - IDE 244 MB
   - Fast SCSI-2 700MB on Buslogic 747C card
   - 486 DX 33Mhz, 16MB RAM

The kernel is booted from the IDE drive.  Only the root and the swap are on
the IDE and everything else is on the SCSI-2 disk.  Would I be better
served to put the swap on the SCSI-2 disk since, as I understand it, IDE
drives require the CPU to do the transfer?  Is this a mute point in that
the transfer to the controller is as fast as the to the SCSI-2 disk using
DMA?  (I know the DMA will free the CPU for other processing.)

This is root's plan, to root out all other roots.
