FreeBSD's ISO ReadMe?

[William C. Testermann]

I am seriously considering switching my Slackware gateway, and workstation over to FreeBSD... I've been wanting to 
try it for a long time... I want to test it on this computer I have and want to know what all ISO's I should make? there is 
4 iso's and a mini, my assumption is at least two of these are source; however I'm not sure... any one got a clue?



                                                Thanks,    
                                                        Testermann
