I had my doubts because gzip'd files usually have the .gz ending, and .img files are usually used for RAW floppy/disk images, afaik.
If they just had some odd naming conventions it doesn't matter :P

your procedure worked perfect. i fixed the problems with the terminal. thanks.

what file and command is responsible for automounting the swap partition, if it exists?

can't i just copy over the software from advanceCD to DSL, including file modes/attributes/permissions/ownership? what would be the problems?

Seems there isn't automatic detection for swap partitions.
So, if you only plan on using that on one computer and know the swap partition, put
swapon /dev/hdXY

right after mounting proc. On the other hand, if autodetection is needed, it might be best to ask the developer.
