Hi,

I tried to update my SUSE SLES 10 SP1 kernel 2.6.16 to kernel 2.6.22.1... that's my first time, so I followed what I was told but now I get grub errror "error13 : invalid or unsupported executable format"

I extracted my linux-2.6.22.1.tar.bz2 file in /usr/src/
then:

zcat /proc/config.gz > .config
make defconfig
make modules-install


and I copied the following files to /boot:
-> cp vmlinux /boot/vmlinuz-2.6.22.1
vmlinuz.2.6.xx are the files used by grup so I decided to rename mine linuz also but when doing a "ls-l" I can see that they are not using the same format...
vmlinux files name police is green and rights are 755 while
vmlinuz files name police is black and rights are 644...
-> cp .config /boot/config-2.6.22.1
-> cp System.map /boot/System.map-2.6.22.1
-> no initrd was created... is that normal?)

Then I modified /boot/grub/menu.lst and added:

title Sebastien 2.6.22
root (hd0,1)
kernel /boot/vmlinuz-2.6.22.1 root=/dev/disk/by-id/scsi-35000c5000034d5a3-part2 resume=/dev/sda1 splash=silent showopts
# initrd /boot/initrd-2.6.16.46-0.12-default

Then I get the "error 13"... I don't know how to modify my vmlinux file to make it supported, has anyone a solution?
Or is there any other way to do it?

Thanks,
sébastien.

Hi sébastien

As you pointed out, vmlinux and vmlinuz are not the same type of file, so you can't just rename one to the other and expect it to work I'm afraid! vmlinuz is actually a compressed version of vmlinux, bundled up with some other stuff which makes it bootable.

Normally it is built for you when you do a "make", and you will find it in arch/(YOUR ARCH)/boot/bzImage

So your steps look correct, except that you should copy your compressed image to /boot instead:

cp arch/`arch`/boot/bzImage /boot/vmlinuz-2.6.22.1

Ok thanks a lot, now it works!

I just executed the line you said:
cp arch/`arch`/boot/bzImage /boot/vmlinuz-2.6.22.1
