If you have a partition on your disk that you are not using, then add it
to the swap space by modifying the /sys/mips/config/HOSTNAME
configuration file: 
config    vmunix  root on rz0a  swap on rz0b
modify to 
config    vmunix  root on rz0a  swap on rz0b and rz0?
where ? is your "free" partition.
Actually, if you have more than one disk, you can also do
config    vmunix  root on rz0a  swap on rz0b and rz#?
where # is the scsi address number and ? the partition you want to use.
