Hi, All I have a debian live cd which starts to boot. I get the ISOLINUX 3.71 Debian-2008-9-06 Copyright notice. Then it just hangs- cd active. Disk is debian-live-502-amd64-gnome-desktop.iso MD5 sums check out...Cd is on-top in bios boot priority. Others, sysrescucd, Ubuntu, Debian testing net-installer all boot fine. I have tried other RW disks. 'may try CD-R disk if no one has a helping guess... TIA Jack
