Installing a new kernel

**kbk** · 01-29-2006

I have decided to install the latest version of the kernel. I currently have 4.6.10, so I think it's about time I upgrade. What I was wondering is, how hard is it, and what settings will be lost? Will my ndiswrapper settings be lost? Thanks.

Anyone? I really need to upgrade, it's just a bit intimidating to me and I don't want to just jump in without enough info..

I think your kernel is already updated, being the 4.xx series and all

jk..

However, since you want to upgrade, I suggest you frist read through this tutorial to get an idea of what to do.

IMO, if you are building a kernel from scratch, it would be better to compile drivers for your peripherials directly into the kernel instead of a module and then modprobing it later. I don't think your ndiswrapper settings would be lost, but since I usually just stick to the kernel which came with my distro I can't say for sure.

hope this helps.

edit:: fixed broken link, thanks ozar.

I followed those instructions to the letter, when I try to load it from GRUB however, it does nothing. Everything seems to be in place.. What'd I do wrong??

Hi, AlexK ... just wanted to let you know that your link to the kernel tutorial is broken in case you want to edit it.

Hello, kbk ... that's the same guide that I followed on my first ever kernel build, and it worked perfectly. Did you edit your /boot/grub/menu.lst (or grub.conf) kernel line before rebooting to make sure it has the proper entries in it? It's been a while since I've run Mepis, so I don't recall exactly how they setup the kernel lines.

thats not a kernel version. unless it is 2.4.6.10 (???).

you may be speaking mepis talk in which i have no idea what you are on about.

compiling your own kernel (from scratch) is a pain until you get used to it.
i wouldnt use a generic kernel for my 2.6.15 kernel ever... not with the 30sec boot time...

I mean 2.6.10, hit the wrong button by accident. I edited the /boot/grub/menu.lst exactly the way it said to on the guide, I also put in the additional commands that come after the other kernels.. So I can't see why it isn't working...

Can you post your menu.lst as well as the output from

Code:

ls -al /boot

and

Code:

df -h

I see the problem you have a space between the (hd0,0) and /boot/vmlinuz-2.6.15.1 and the (hd0,0) and /boot/initrd.splash. The stanza for the new kernel should read:

title kernel 2.6.15.1
kernel (hd0,0)/boot/vmlinuz-2.6.15.1 root=/dev/hda1 nomce quiet splash=verbose vga=791

intrd (hd0,0)/boot/initrd.splash

If you still have problems report back.
