KErnel not showing all my memory

    My kernel is only showing 886 of the 2048 MB memory.

    I know that for Mandrake there are up 1GB kernels and they work great on my other system with 2GB. I have been lookig for this kernels for Debian but haven't found a good place.

    Can somebody help me with this. How can a change the current 2.6 kernel to support the full 2GB memory, or where can a find a up 1GB kernel for Debian?

    Thanks for your help

    What's the output of
    Code:
    uname -a
    and
    Code:
    apt-cache search linux
    ?

    The text was to long so I only posted the part of the kernel. Do you need the whole text or is this enough.

    I got the 2.6 kernel after updating the net install 2.4 that also wasn't supporting all my memory.


    Thanks for helping Falko

    Thats awsome... im doing the same thing with suspend ram and all i had to was to customise my kernel and allow a few PCI... theres a website that showed me what to do...

    You could try to install kernel-image-2.6.8-12-amd64-k8 then.

    Is a AMD64 kernel working also on a 32bit system then? The Athlon XP is 32bit and the processor is called the K7.

    Oh, I'm sorry. I read Athlon and thought this is a 64-bit Athlon...
    You're right, this won't work. You can try to install kernel-image-2.6.8-3-k7 instead.
