Slackware SMP kernel on Dell PE 2850

I am running Slack 10.2 stock kernel from "raid.s" on a Dell PE2850, 2 processor core duo, 4GB RAM and it runs fine. I just do not have access to the full RAM and multi-processor capabilities of the server. I was trying to reconfigure the kernel to enable SMP and RAM up to 4GB.
Once compiled, and changes are made to "/etc/lilo.conf", it boots showing 8 processors, runs through the SCSI init using MegaRAID2 in the kernel, then right after the Detecting Hardware line it throws "Unable to handle kernel paging request at <I did not write the memory location down, sorry>".

To get to this point, I copied "/boot/config" to "/usr/src/linux/.config" and made the changes for RAM up to 4GB, and SMP using "make menuconfig", compiled the kernel, and placed it in the "/boot" dir, then modified "/etc/lilo.conf" and ran lilo.
I thought that this would give me the config from the current running kernel, but apparently it does not because the system does not complete a boot. I got the error mentioned above, (module problem?).
I tried "make dep", "make modules", "make modules_install". Still same problem.

Is there a way that I can get a .config from the running kernel and just make changes for the RAM and SMP options?

Any help is greatly appreciated!

If you are using a stock Slackware, in the /boot section you have the config (or config-ide-something) file of the original 2.4.x kernel the OS comes with. That is a good starting point if you want to recompile the kernel.

If you switch to a 2.6.x kernel and the config.gz option is set, you can easily see the config of the running kernel in /proc/config.gz. You can see it with the command less.

Hope it helps.

I was afraid of that...I used the /boot/config to start from, made changes for SMP and RAM up to 4GB, then compiled the new kernel.
It still won't complete a boot. I get that kernel paging error.
I am using kernel 2.4.31

Thanks for the info... Trying again tonight.
