1) Boot DSL and open a terminal window.
2) Type:

sudo su
cfdisk /dev/hda

(where hda is the device name for your hard drive)

3) Use cfdisk commands to create a new partition type "Linux swap". Remember the location of this partition. For this example, it is partition number 3. Write the new table and exit.

4) Type:

mkswap /dev/hda3
exit
exit

5) Reboot, and DSL should automatically detect the new swap partition.
