    Knoppix won't boot

    After I type knoppix to boot from the cd, I get the following error messages and the computer hangs:

    Initrd extends beyond end of memory
    Kernel panic: VFS: Unable to mount roots fs on 01:01

    I currently have Windows XP installed.

    This is from the doc section on this site - from the cheat codes (which specify different boot options).

    "mem=128M
    Specify Memory size in MByte, Some Boards apparently don't pass the proper memory size to the linux-kernel. It may cause the message "Panic cannot mount root file system" and the system hangs. Use "knoppix mem=128M" to solve that problem if your system has 128MByte memory for example (caution you MUST use a capital "M" here)."

    So at the boot screen type:

    "knoppix mem=(whatever_your_mem_is)M"

    Please post back whether or not this fixes your problem. There may be other issues to consider, but this is a good start.

    Have you used this cd sucessfully on any other computers? Try running "testcd" at the bootup screen and see if it's a good disk. You might need to download the image again if it's corrupted. You could also try burning at a slower speed as some have said that this has fixed similar problems.
