how can I switch kernel, SlackWare 13.37
 
I am trying to boot my slackware installation with the generic kernel. I need to see if that will fix my wireless connection problems.

Currently I have been booting using the huge kernel here is the slakware entry in grub
Code:
###Don't change this comment - YaST2 identifier: Original name: linux###
title SlackWare 13.37
    root (hd0,4)
    kernel /boot/vmlinuz-huge-2.6.37.6 root=/dev/sda5
    initrd /boot/vmlinuz-huge-2.6.37.6
that entry works fine but the kernel is not loading the right driver for my wireless card

I added another entry to boot from the generic kernel and this is how it looks
Code:
###Don't change this comment - YaST2 identifier: Original name: linux###
title SlackWare
    root (hd0,4)
    kernel (hd0,4)/boot/vmlinuz-generic-2.6.37.6 root=/dev/sda5
    initrd /boot/vmlinuz-generic-2.6.37.6
the boot starts but then goes into a panic and stop.
My question is what should I change to make it boot using the generic kernel?

I will appreciate all advice. Thank you!

The problem is this line "initrd /boot/vmlinuz-generic-2.6.37.6". That is not your initrd, it is your kernel. Make an initrd file using the directions in README.initrd within the /boot directory and then specify that instead.

And huge doesn't typically use an initrd but you have specified one (again your kernel, which was wrong). So your original setup was incorrect as well.

Thank you for the information. I went to create an initrd.gz file base on the instructions and came and changed my entry here is how it looks now
Code:
###Don't change this comment - YaST2 identifier: Original name: linux###
title SlackWare
    root (hd0,4)
    kernel /boot/vmlinuz-generic-2.6.37.6 root=/dev/sda5
    initrd /boot/initrd.gz
I still get a panic message when trying to boot using that file.

So I will really appreciate it all advice.
Thank you.

Which filesystem is on your /-partition and which command have you launched exactly to create the initrd?

TroN-0074 06-30-2012 01:13 PM
O.k so my / is formated in ext4 and to create the file I cd into /boot as root and issued the command # mkinitrd twice

If the file was wrongly created I can go and modify it.

I will appreciate it all advice. I feel I am swimming in deep waters here. Thank you

You have to build in the modules needed to access the filesystem
Code:
mkinitrd -m ext4
This will automatically pull in some other modules, don't worry about that. After that, try it again.

Thank you! That worked. I re created the file and now I was able to boot with the generic kernel, however it didn't fix the wireless problem.

I really appreciate all the help provided to solve this thread

Glad it worked out for you in the end. Though I can't help but mention that README.initrd tells you about the switches to use (e.g. '-m'). ;)
