kernel options

Hi

Ive just been looking in the /boot directory in redhat9 and see the config-2.4.20-9smp file. It looks like it contains some settings but i havnt found any docs explaining what they all are. Is there anywhere which lists / explains all the relevant options in this file?

thanks

It's kernel options. If you download the 2.4.20 kernel, or have the source already existing in /usr/src then you can copy that config file over to that directory:
cp /boot/config-2.4.20-9smp /usr/src/linux-2.4.20/.config
And load it up with your kernel config. The options from the config file will have been chosen, then it's simply reading the help files associated with those options for more info.

fyi, smp is for dual cpu systems.

Cool

So am i right in thinking that just changing the options in the file in /boot will not have any effect, id actually have to recompile the kernel for them to take effect?

Yes, that is correct. That config file will setup your kernel options for you, then you just have to make dep, clean, modules, modules_install, bzImage OR vmlinuz
