What are all these different images

[meazz1]

I am new to the forum.
can somebody explain to me what are the differences between all these images? Which one do I need to runa a firewall and wireless AP.
Can I install a 4 gig image on a 4 gig CF?
I just bought a PC Engines Alix2c10 board, a 4 gig CF and an Atheros AR5213A Super G 108 Mbps Mini PCI wireless card.

All images contain the same software, the size is only important for the CF size you're using. IIRC all images are slightly smaller than their respective size and should fit on a same size CF. If that's not the case, just write the smaller version (2G) to your CF.
