Hi all,
I want to switch from SL 6.2 to SL 7.4 (fresh install, not upgrade).
In http://ftp.scientificlinux.org/linux/scientific/7x/x86_64/iso/
I see several iso files, but cannot understand which one fits my needs.
I would like to keep a bootable DVD (not dual layer) copy and a live disk.
Which are the right files to download?

Thanks
