I see in the official download website FreeBSD6.2-Stable there are 4 .isos to donwload:

"6.2-RELEASE-i386-disc1.iso
573.4 MB (FTP) (HTTP)
6.2-RELEASE-i386-disc2.iso
639.1 MB (FTP) (HTTP)
6.2-RELEASE-i386-bootonly.iso
24.3 MB (FTP) (HTTP)
6.2-RELEASE-i386-docs.iso
187.9 MB (FTP) (HTTP)"

Anyone can tell me if I need all of them? I want to set up FreeBSD with Fluxbox and packages, I do not understand why there is one .iso called bootlonly of 25MB and another .iso called docs of 190MB only, it would make sense to me to put all those together in the same .iso and not to waste a CD with something that small in size.
