    Thx Jonathan for ur help
    .
     I got the kernel(2.4.28) from kernel.org and started
    recompiling.

    My steps:

    cd /usr/src/linux-2.4.28
    cp /boot/config-2.4.18-smp .config
    edit .config and include CONFIG_HIGHMEM=y &
    CONFIG_HIGHMEM4G=y

    make-kpkg --revision=debian.2.4 kernel-image

    Then it prompts lot of questions like the format as
     CONFIG_SMP=y (y/n...) (NEW)

    What should I do for all these questions?

    I know what config_smp will do,but most of other
    options I don't know. So How do I proceed?
