Help with Kernel install.

Help with Kernel install.

[Thomas Ward]

Hello, list. Today I have been having some problems getting a 2.2.18 Kernel
working.
I have downloaded the Speakup v-0.10 source, and have successfully applied
the patch to the Linux 2.2.18 Kernel source tree.
However, while building the bzImage I have been getting some warnings, and
then after word as might be expected the kernel will boot but then go into
Kernel panic.
I have been trying to boot it off of a boot disk just for this vary reason.
I don't want to kill my working 2.2.16 Kernel until I know the 2.2.18 will
work.
If I believe the exact error was:

"root file system not found at 03-02."
How do I direct the Kernel to /dev/hda1 I tried the Linux root=/dev/hda1
command for some reason it is still giving me that error.
Thanks for any help you might have.

If I understand what you're asking do an 'rdev /dev/hda1'.  Usually
that is what is set automatically unless your primary is not on hda1.
Try to give us more information.  There is the possibility that you
didn't include the correct drive configuration options.

good luck
  Kirk

You can setup to boot with a new kernell without endangering your current
situation. If you copy the new bzImage to the /boot dir and add a new
entry to lilo.conf. Just copy the curent entry with a new label and new
image name. you will then have an option of shoosing the image to use when
you first boot.

It sounds to me like the kernel panic is not a problem with the kernell
itself, but rather that it is failing to find a usable root location for
the file system. Chances are that unless you have one large partition on
your drive the correct root partition is /dev/hda4 or /dev/hda5. You can
pick it out by running the mount command or df.

Hello, Kirk. Well, I was hoping to install this Kernel on multiple machines.
On my laptop it is /dev/hda2
On my desktop system on my hard drive it is /dev/HDA1.
I manually fdisked and mapped out these partitions myself when I installed
RH 7 so that much I know.
I guess I want to know how to set the Kernel up so I can just drop it onto a
partition of my choosing, and also turn it into a rescue boot disk.

Hi:

Well, there is a root directive in /etc/lilo.conf.  Whether this over-rides
any other specifications (e.g. rdev, command line, etc), I am not sure.  So
you could use different /etc/lilo.conf files on your different machines to
specify the particular root partition.  You will of course have to have the
correct root device set for a bootdisk kernel, as it will need to find your
root partition upon boot-up.

Geoff.

Hi Tom:  I think what you may be looking for is the rdev command.  If
you are going to place a kernel on a floppy then use rdev on an image
to set the root device and then move it to the floppy with 'dd if=kernelfile
of=/dev/fd0'. 

Man rdev will give you the various arguments you can use.

Hi,
		Try just dd-ing your kernel to a bootdisk.
