where is kernel? still boots to 2.4.31 after make 2.6.16.1

ctos · 04-04-2006, 06:28 PM

Hello! I downloaded source for 2.6.16.1. After configure, make bzImage, make modules, make modules_install, I went into /boot, removed symlinks System.map, config, and vmlinuz; I copied the new System.map and config files into /boot with 2.6.16.1 appended to their names, and from /usr/src/linux-2.6.16.1/arch/i386/boot I copied bzImage to /boot/vmlinuz and added -2.6.16.1. Then I added symlinks for System.map-2.6.16.1 and for config-2.6.16.1 and vmlinuz-2.6.16.1. This is how I always update the kernel. I keep lilo.conf the same. It reads:

Code:

image = /boot/vmlinuz
  root = /dev/hdc2
  label = Linux
  read-only # Non-UMSDOS filesystems should be mounted read-only for checking

Here is my directory listing of /boot:

Code:

total 2620
drwxr-xr-x   3 root root     376 2006-04-04 19:03 ./
drwxr-xr-x  18 root root     488 2006-04-03 18:12 ../
drwxr-xr-x   6 root root     168 2006-04-04 19:00 Old/
lrwxrwxrwx   1 root root      37 2006-03-21 21:32 README.initrd -> /usr/doc/mkinitrd-1.0.1/README.initrd
lrwxrwxrwx   1 root root      19 2006-04-04 19:03 System.map -> System.map-2.6.16.1
-rw-r--r--   1 root root  805960 2006-04-04 19:01 System.map-2.6.16.1
-rw-r--r--   1 root root     512 2006-03-21 21:52 boot.1602
lrwxrwxrwx   1 root root      15 2006-04-04 19:03 config -> config-2.6.16.1
-rw-r--r--   1 root root   41156 2006-04-04 19:01 config-2.6.16.1
-rw-r--r--   1 root root    5032 2004-05-21 07:19 diag1.img
-rw-------   1 root root   26624 2006-04-03 18:12 map
lrwxrwxrwx   1 root root      16 2006-04-04 19:03 vmlinuz -> vmlinuz-2.6.16.1
-rw-r--r--   1 root root 1784070 2006-04-04 19:02 vmlinuz-2.6.16.1

So lilo.conf should just read in the 2.6.16.1 kernel. I didn't make a mistake and reinstall the 2.4.31 materials because they all have different file sizes.

Code:

drwxr-xr-x  2 root root     152 2006-04-04 19:01 ./
drwxr-xr-x  6 root root     168 2006-04-04 19:00 ../
-rw-r--r--  1 root root  609687 2006-04-03 18:16 System.map-2.4.31
-rw-r--r--  1 root root   37120 2006-04-03 18:17 config-2.4.31
-rw-r--r--  1 root root 1257191 2006-04-03 18:17 vmlinuz-2.4.31

How should I make the system boot to the 2.6.16.1 kernel?

Did you run lilo? I know I've forgotten to. Plus, just in case, you should leave the old kernel and add to lilo.conf just in case the new one is unbootable.

Code:

prompt
timeout= 50 #Gives you 5 seconds to choose
image = /boot/vmlinuz
  root = /dev/hdc2
  label = Linux
  read-only 
image=/boot/vmlinuz-old
 root= /dev/hdc2
 label= Old Kernel
 read-only

Change vmlinuz-old to whatever yours is.

Oh.

I've never had to run lilo before. I went from 2.4.something to 2.4.31 without running lilo. Or maybe I ran lilo and forgot.

Anyway, my computer booted to 2.6.16.1. But, the consoles were invisible. I had to log in blind. They didn't become visible later. Also, my Internet connection (PPPoE via Verizon fiber with DHCP enabled (my computer->hub->router) via Ethernet) got blasted. I thought I had enabled appropriate networking options in the configuration. I couldn't ping the router.

You have to run lilo EVERY TIME you change kernel/lilo.conf

ctos · 04-04-2006, 07:29 PM

Okay. But I didn't actually change lilo.conf. I changed the files in /boot that lilo.conf points to.

masonm · 04-04-2006, 07:58 PM

Doesn't matter, you still HAVE to run lilo.

Did you enable the VGA mode in the kernel configuration?

Device Drivers -> Graphics support -> Console display drivers support -> VGA text console

Make sure it's enabled [Y].

Thanks for your help again. Another problem tonight is I have now lost my double-tap touchpad feature, and the e-z scroll. It was working since I compiled 2.4.31 (I think that's when it started to work but I'm not exactly sure). Now it doesn't work.

Under "Console display driver support" I have these options:

--- VGA text console[*] Video mode selection support
< > MDA text console (dual-headed) (EXPERIMENTAL)
<*> Framebuffer Console support

I have just now added the Y to the last one. When I returned to make menuconfig just now to write this post, it was blank. Only "Video mode selection support" was selected. Do you think that'll cover it?

I can't get it to format correctly but of course "[*] Video mode..." is on a separate line.
