Other Help Topics :: Differences between distrs

Sorry, people, stupid question.
I've found at ftp several DSL distributions:
(http://distro.ibiblio.org/pub/linux/distributions/damnsmall/current)
dsl-1.2-syslinux.iso
dsl-1.2.iso
dsl-embedded-1.2.zip
dsl-embedded.zip

What are the differences between them. I'm looking for distribution for embedded PC (Geode GX1). What DSL flavour could you recommend me?

Thanks!
