thanks for this help. I'll first try the PCMCIA and if I can't have it work (or boot...) then I'll try to convince my teachers to change the adapter for a more 'standard' one like for the flash cards as you said. So the ramdisk seems a good idea, great, I'll try this too. But I'll probably have to set a writeable fs on the flash too, to store some data like pictures or data concerning the average speed, the track that the robot followed, etc. But let's don't hurry too much! I must admit I didn't really
meant to install peeweelinux, but rather build the system from scratch, but after all I'll give it a try in the next few days to get confident about the embedded world!
thanks again guys!

You can always take your application and compile it as static if there are some funky incompatabilities with what peewee installs (for instance, I compile a GTK+ program as static, and it si 3MB in size but I don't have to install GTK+ on the embedded system..)
