Comments on: Compiling a new kernel http://www.designlegion.com/linux/compiling-a-new-kernel/ Tue, 06 Jan 2009 05:46:59 +0000 http://wordpress.org/?v=2.6.2 By: Lewis http://www.designlegion.com/linux/compiling-a-new-kernel/#comment-87 Lewis Thu, 16 Nov 2006 20:21:57 +0000 http://www.designlegion.com/linux/compiling-a-new-kernel/#comment-87 Matt, When you installed Slackware, you most likely used the default kernel which has great support for IDE based drives but limited support for SATA drives. Using my config enabled the support for SATA (sda) but your system is still configured for IDE (hda). You got the kernel panic because the kernel was looking for /dev/sda in lilo.conf but you fixed that. The next problem is you can only mount in read-only because the file systems table (fstab) is looking to mount a /dev/hda drive. You need to edit <strong>/etc/fstab</strong> and change the hda values to sda. Doing that will allow your system to mount the correct drive with the correct configuration, but... Your drive is read-only so you cannot save changes to fstab. You will need to insert the Slackware CD/DVD and reboot. At the boot prompt type: <code>huge26.s</code> When prompted, select your keyboard map and login as <strong>root</strong>. From here, you can mount your linux filesystem <strong>/dev/sda3</strong> with this command: <code># mount /dev/sda3 /mnt</code> Now we can edit <strong>fstab</strong> with <strong>pico</strong> or <strong>vi</strong> (I use pico): <code># pico /mnt/etc/fstab</code> Here, you'll see the drive/partition configurations, just replace any <strong>hda</strong> with <strong>sda</strong>. When you're done, press CTRL+O, then hit enter to write the file to the harddrive. Press CTRL+X to exit and reboot the system. You should be booting normally. Matt,
When you installed Slackware, you most likely used the default kernel which has great support for IDE based drives but limited support for SATA drives.

Your drive is read-only so you cannot save changes to fstab. You will need to insert the Slackware CD/DVD and reboot. At the boot prompt type: huge26.s
When prompted, select your keyboard map and login as root. From here, you can mount your linux filesystem /dev/sda3 with this command:
# mount /dev/sda3 /mnt
Now we can edit fstab with pico or vi (I use pico):
# pico /mnt/etc/fstab
Here, you’ll see the drive/partition configurations, just replace any hda with sda. When you’re done, press CTRL+O, then hit enter to write the file to the harddrive. Press CTRL+X to exit and reboot the system.

You should be booting normally.

When i do a recompile of the kernel with 2.6.*, if i set lilo.conf to /dev/hda3, it wont boot (Kernel Panic, blah, root(3,3) not found). So i figured out that lilo.conf needed to be changed to /dev/sda3, but then the problem is that e2fsck still tries to check /dev/hda3 (which does not exist becuase it is seen as /dev/sda3) and wont let me boot anything but read only mode. hmph. I used: kernel 2.6.17.13 with your config on a dell m1210 (nearly the same hardware config as yours) I seem to be having some trouble and im not quite sure why.

You should have bluetooth... blue led under the power indicators. If not, it won't be a problem as the bluetooth modules won't cause any compatibility issues. Glad it worked for you.

When the kernel modules are installed, a link will be created from <strong>/lib/modules/build</strong> to <strong>/usr/src/linux</strong>. Another thing, make sure you install the <strong>kernel headers</strong> for 2.6.17.13. Check your Slackware 11 cd in the '<strong>/extra/linux-2.6.17.13</strong>' folder. /usr/src/linux is only linked to /usr/src/linux-2.6.17 or whatever the kernel source version is.

Does the link linux in /usr/src/linux have any other links to like another system folder other than the link we make...because i did an install with out kernel sources..because i couldnt config any other kernel than the one supplied 2.4.3.3 or somethin... thanks trying it now…i have one more question… Does the link linux in /usr/src/linux have any other links to like another system folder other than the link we make…because i did an install with out kernel sources..because i couldnt config any other kernel than the one supplied 2.4.3.3 or somethin…

I have the nVidia card, the Intel wireless, Intel audio, same host and pci bridges. I just need to post an updated lspci. Try my config though, it should fix all your problems. It's most likely you just missed an important option while constructing your config file. None of those differences will affect the kernel booting process.
