Running demo's? Which ones? I haven't seen any demo's for AROS. I know there is one to be released soon, but AFAIK there are none currently. MPlayer is coming soon too.
This is taken from the AROS site itself:
i386-linux-system
The hosted version for Linux/i386. This is the most complete and mature port, which means that you can run all included programs and demos with it. This archive contains all AROS system binaries compiled from the CVS tree.
And i have also seen a video demo of aros running some small gfx demos, which i believe i also downloaded from the AROS site some months ago.
It didnt have networking added the last time i checked, but i think it is very good news that it is added now.
