you need to create a swap partition... it should be easiest to shrink your last partition by say, 250mb using resize2fs or resize_reiser depending on your choice of fs, then partition the newly freed space as linux swap in cfdisk or fdisk. then use mkswap /dev/hda9 (for example) to create the swap. you should then be able to test it using "swapon /dev/hda9" and if that works and "free" reports that right amount of swap, add an /etc/fstab entry:
Code:
/dev/hda9 none swap sw 0 0
