    Here's a query i got from a friend - does this seem correc?
    I am currently using SUSE 9.3 but want to put the kernel for SUSE 9.2 on the system to see if something works
    Not sure the exact method to use

    This is what I found so far

    Open YAST add packages gcc and ncurses
    Cp the new src directory to
    /usr/src/linux-2.6.8-24.10
    Make menuconfig
    Make clean
    Make bzImage

    cp arch/i386/boot/bzImage /boot/bzImage-2.6.8-24.10
    cp System.map /boot/System.map-2.6.8-24.10
    ln -s /boot/System.map-2.6.8-24.10 /boot/System.map
    Cp boot/grub/menu.lst boot/grub/menu.lst_orig
    Edit boot/grub/menu.lst to contain title Test Kernel (2.6.8-24.10)
    root (hd0,1)
    kernel /boot/bzImage-2.6.8-24.10 ro root=LABEL=/
    initrd /boot/initrd-2.6.8-24.10.img

    should be:
    make clean
    make menuconfig
    make bzImage

    "make clean" clears the config file that you created with menuconfig so if you were to run it second ye use your custom kernel config.

    other option to do after make bzImage is to say "make install" it's been awhile since i've rolled my own kernel but if i recall this generally goes and installs kernel images etc in /boot and modifies the boot loader.

    I'd be more inclined just to copy the kernel over from a 9.2 box,
    and not get it involved with Yast. Yast will decide to make
    a b***ox of things for you within minutes if you interfere
    with something like the kernel.

    Just copy the kernel over:
    [b]On the 9.2 box[/b]
tar czvf /suse9.2kernel.tgz /boot/*2.6.8-24.10 /lib/modules/2.6.8-24.10

    Then copy the file to the 9.3 system and 
    [b]On the 9.3 box[/b]
tar xzvf /suse9.2kernel.tgz -C /

    Edit the grub.conf or lilo.conf as per the original post,
    and give it a restart.

    If you don't have a 9.2 box, open up the kernel rpm using alien or similar
    and install the files manually in a similar way.

    Just 2¢.
