I am trying to install CentOS 4.7. When I get on to the mirror site, it offers me different binaries, bin1of5, bin2of5,bin3of5, etc. I just want the basic version. Which one should I download?
Download bin1of5, if it is like later releases, you can install a minimal system from that. You have to deselect all package-groups (including "Base") during the initial stage of installation. After booting the new system, you can install any required package-groups from the Internet repositories using
yum groupinstall package-group-name.
