I'm sorry for my ignorance with my last reply. I see what you are asking me now :-) It is indeed possible to read your current config options!! If you take a look in the folder "/boot", you should see a file called "vmlinuz.config". If you take a look at this file, using a

Check whether you're using a 2.2 or a 2.4 kernel for a 2.4 kernel it's called /boot/vmlinuz_2.4.config (or somesuch) Copy this to /usr/src/linux/.config (after making sure that /usr/src/linux points to the correct kernel sources) also copy vmlinuz_24.autoconf.h to /usr/src/linux/include/linux/autoconf.h and vmlinuz_24.version.h to /usr/src/linux/include/linux/version.h

text editor such as jed or emacs, this should list all your config Learn vi .

Vi is available on all Unix flavours, whereas emacs and jed are not.

It worked. Thankx all! Daryn

You can also run: make cloneconfig Which will make a kernel with the current running configuration using the config.gz in /proc.

I'm not certain I understand what you mean by "make changes during that call"? I usually use it like so: make cloneconfig make menuconfig (to make any changes to the cloneconfig) Cheers, Leah dc@k-net.de (dc@k-net.de) [010606 07:21]: - > - > > You can also run: - > > - > > make cloneconfig - > > - > I'm not so informed, but isn't it so that you cannot make changes during - > that call.

I'm not positive, but I don't think it does much more than that. The same effect could probably be achieved by doing:

zcat /proc/config.gz >> /usr/src/linux/.config make menuconfig I just try them both out on my test maschine and see what happens.

Thankx for the info. Daryn

What precisely is the difference between 1) make oldconfig

and 2) make cloneconfig Specific to SuSE kernels. It will create a .config file based on the current running kernel. For example yopu have installed a SuSE compiled kernel and you want to change things starting make cloneconfig will dump the kernel configuration from the memory /proc

start configuring the kernel based on your previous settings that means you do not have to go over every single option again again. directory and then you will have to configure your kernel the same old way. It is a time saver IMO

mv /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz mv /usr/src/linux/System.map /boot/System.map /sbin/lilo

use of make bzlilo will save all those steps HTH -- Togan Muftuoglu
