    Boot issue: undefined mode number

    Hello everyone, I just started playing with Linux. The first experience was with Knoppix 3.2. When I boot the cd I get the following message:

    "You Passed an undefined mode number
    Press <return> to see video modes available
    OR
    Press <space> to continue or wait 30 secs."

    If I press the space bar it continues booting. And it boots fine. No problem with the video, Just this nagging prompt each time I boot. Press the space bar or else you have to wait 30 secs. I have also installed knoppix 3.2 on the hard drive. It runs good but the prompt above still appears. Does anyone have any fixes for this. I searched around and came up with nothing.
    Thanks in Advance ....KnoppixBill

    PS alittle info which may be helpful?
    I am running Knoppix 3.2 on a Dell Dimension L550r
    The Video is built into the motherboard. Its old and slow
    But its works fine and is refreshing. I think I will begin to
    migrate over eventually. Linux has so much more to offer.

    Boot issue: undefined mode number

    Try the "knoppix vga=normal" cheatcode at the "boot: " prompt.

    Hi Bill,

    did you try <return> to see your video modes? If you found the best mode you can add it as "vga=<YOUR_MODE>" into the append line in file /etc/lilo.conf. Don't forget to run "/sbin/lilo", et voila - knoppix should start fine.

    Ciao Martin

    Thanks for the info guys. I ended up editing the lilo.conf file. The very first line was vga=791 I replaced 791 with normal and it boots fine now!!
    Thanks again,
    .....KnoppixBill
