Knoppix 6.2 doesn't boot straightaway if the computer has one of the newer wide TFT screens as the monitor eg 1366x768 or 1920x1080 pixel ratio = i have tried these two. You have to specify the screen size option in boot option boot: knoppix screen=1920x1080 etc for the boot process to complete. knoppix has to invoke the video adapter software from the packed on CD/DVD software. yegna
