Older releases are available through the Salix project page at Sourceforge.
If instead of the iso images, you are looking for the packages that are included in the Salix repositories, you can download them through one of our repository mirrors.
The iso images that are available for download here are not Live images. They boot into the standard Salix installer, which is a text-mode dialog-based installer.
