I tried compiling my kernel, as a learning exercise. I followed the sticky found here. I added the lines below to the lilo.conf file, to be able to boot into teh old kernel,but I still only have the one Linux option when I boot. I can boot, but I would like to know why the slack.old was not added to the boot choices. Am I skipping something? Any suggestions?


Add this to your config...you can just copy what is there and add the .old stuff.

image = /boot/vmlinuz.old

root = /dev/hda1

label = slack.old

read-only

If things did not go completely according to plan you can boot your old (working)
kernel by selecting slack.old at the lilo screen.

Did you ran after making the changes to /etc/lilo.conf

You probably did not run lilo after lilo.conf modification. You must do that afer any lilo.conf modifications in order they are actually registered.
as root try
lilo -v -t
-v is for verbose. just to see what happens
-t is for test. Just test, no modifications at all.
If no errors are reported again
lilo
and you should be after.
Sorry, but I suspect you are messing a bit your system.
After new kernel compile you will have three files you need from the kernel source directory. (not exactly, but let's assume this is fully true).
/usr/src/linux-2.6.16.9/arch/i386/boot/bzImage
/usr/src/linux-2.6.16.9/System.map
/usr/src/linux-2.6.16.9/.config ----------------> this is an hidden file
rename them acording to your needs (ie bzImage-2.6.16.9 etc)
and copy them into your /boot directory
edit your /etc/lilo.conf just adding a section like

image = /boot/bzImage-2.6.16.9
root = /dev/hda6 ---------------------> this must be modified according to your needs
label = Linux-2.6.16.9
read-only

Do not modify anything else.
Run lilo as said before
Hope this helps

Thanks for the replys. I did not run lilo after the compile. I just rebooted. I'll try that when I get home tonight.

I am using the 2.4 kernel that came with 10.1, so I am not sure those files apply. As for messing up the system, I'm sure I will. But thats OK. Worst case, I'll reinstall and start over. I have used Slackware for about a year now, but never went deeper than installing Open Office. I would like to understand more about the kernel, and compiling applications. The only way I know how to learn is to try. Thanks again, and any suggestions are appreciated.

You're in the right direction....
