i want to use swap file, but dsl does not seem to recognise my swap partition. i have hda1 set up as my boot partition (Linux ext2), and hda2 partitioned for a swap (Linux swap). the first partition is 1550.36 MB and the second partition is 561.52 MB. i'm also unable to get hda2 to mount. any suggestions?

You can't mount a swap partition..
It's type 82=swap , not type83=ext2

Did you run mkswap /dev/hda2 ?
Did you run swapon /dev/hda2 ?

Does cfdisk show the 2nd primary partition as type 82=swap ?

Did you do all of these items as root ?

Your post spoke of a "swapfile".....
Do you mean a "swap partition" . right ?

You can also create a SwapFile in case you dont want to partition the harddrive.

Swap files    Swapping to files is usually slower than swapping to a raw partition, so this is not the recommended permanent swapping technique.  Creating a swap file, however, can be a quick fix if you temporarily need more swap space. You can have up to 8 swap files, each with size of up to 16 MB. Here are the steps for making a swap file:    - Create a file with the size of your swap file:    dd if=/dev/zero of=/swapfile bs=1024 count=8192    This physically creates the swap file /swapfile, the block size is 1024 bytes, the file contains 8192 blocks, the total size is about 8 MB. [The dd command copies files. In the example above, the input file (if) was /dev/zero, the output file (of) was /swapfile . You cannot use the cp (copy) command for creating a swap file because the swap file must be physically continuous on the hard drive.]    - Set up the file with the command:    mkswap /swapfile 8192    - Force writing the buffer cache to disk by issuing the command:    sync    - Enable the swap with the command:    swapon /swapfile    When you are done using the swap file, you can turn it off and remove:    swapoff /swapfile    rm /swapfile

Hope this helps
