There aren't a whole lot of options in those bios's, though, and I saw at least four completely different versions, so I don't think I would have overlooked that. Most of the machines (I think all of them, actually) started to boot Centos 6 to at least some extent. They just failed (lock up, kernel panic, etc) somewhere along the line after that. And Centos 7 did work on the third one that I tried. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
