Slackware 10 SMP

Hi All,

I have an SMP machine and would like to recompile the kernel to enable it. Actually that is the only change I want to make to kernel. So can I basically do something like this:

untar the linux kernel source from one of the CD's (Do not use /usr/src/linux because it iw for the kernel headers)

cd to source directory.

make mrproper

make oldconfig

make xconfig

// do the changes

make dep

make bzImage

Does that sound about right? I dont want to have to recompile all the modules or anything.

And how do I handle the initrd/system.map etc.

Thanks,
Sam

Hi,
What version of the kernel are you using?

Here's what you can do:
untar the kernel source.
Copy the config file from the CD in them kernels/bare.i folder and put it in the Kerenel source directory called .config.

For the 2.6 kernel.

Code:

make oldconfig
make menuconfig
make

For the 2.4 kernel, use:

Code:

make oldconfig
make menuconfig
make deps
make modules
make modules_install

Now, copy the new kernel from arch/i386/boot/bzImage to /boot/kernel-smp

Edit your /etc/lilo.conf to use your new kernel (Make a new entry, and keep the old one incase something goes wrong).

Run the lilo command and reboot!
