First, this set is of older version, there's new version of OpenSUSE 11.4 Linux, 4-Disks DVD Installation and Reference Set Ed. 2011
And the new set is way beeter than this old one. It is complete with all installation files on DVDs wit reference books, moreover it included breif into to Linux on video-DVD. Speaking of this older 11.2 version, it had its share of problems and it wasn't the greatest release from open suse. I had numerous issues with drivers, installation etc (it was fixed in 11.3). The new 11.4 is neat and fast and recognized all devices on my three computers. It even regognized my laptops webcam and usb radio tuner. In short: this is two releases behind so get the new version.
