Hi whole thread follows, and they are authoritive words <smile> What I found to be easy, first I used a flash-boot disk (diskless have them) or for a laptop a USB boot stick. I made it work, but grub was a pain and not reliably repeatable, but syslinux works and is kewl. Put LTSP on local media. Fast nice. James
