the complete steps are very long, but for starters, go to the file with the download and extract it if so required, then type make menuconfig select all the modules and support the kernel will need, after that, just

Code:

make && make modules_install

at least in gentoo thats how its done, i cant say if its differnt in other distros. After that you will have to copy the bzImage and System.map onto your bootable partition. then its just a matter of configuring the bootloader to have an option that alows you to boot either kernel.

this will depend on which kernel you are compiling. is it the 2.4 or the 2.6 kernel?? cause what gub333 said will work for the 2.6 kernel but not the 2.4 i cant remember what the 2.4 compile commands are but im sure someone else will. but let us know which version of the kernel are you compiling

doi! my mistake, i only recently compiled my own kernely, but the command for compiling a 2.4 are as follows

Code:

make dep && make bzImage modules modules_install

hope all goes well!

I'm trying to put the 2.6.7 kernel into fedora core one. I go about the precedures up to "make && make modules_install" except it's "make bzImage && make modules modules_install"I finish that, and then i just do "make install" the readout from this is as follows:

Code:

make&#91;1&#93;&#58; 'arch/1386/kernel/asm-offsets.s' is up to date.
 CHK   include/linux/compile.h
Kernel&#58; arch/i386/boot/bzImage is ready
sh /usr/src/linux-2.6.7/arch/i386/boot/install.sh 2.6.7 arch/i386/boot/bzimage system.map
""

No module ata_piix found for kernel 2.6.7, aborting.
mkinitrd failed
make&#91;1&#93;&#58; *** &#91;install&#93; Error 1
make&#58; *** &#91;Install&#93; error 2

Back to your quote, i am wondering if this is due to me not copying the bzImage and system map to the bootable partition and configuring the bootloader. If this is so, How do i do it?
Thanx a whole lot in advance

Spex:
Distro: Fedora Core 1
Bootloader: Grub
Current kernel:2.4.22
Kernel i'm trying to install:2.6.7

you already made, you dont need to make install again, just copy the bzImage to your boot, name it whatever you want qubkernel for exampl, then copy the system.map to the boot with the name (in this example) System.map-qubkernel. Then you add to you bootlaoder (should it be grub, i dont rember for lilo)

Code:

title=qubkernel
root=&#40;hd0,0&#41;
kernel /qubkernel root=/dev/hda4

btw, the bzImage will be in something liek arch/i386/boot but it differs, and make sure you have your boot partition mounted, some people/distro's dont do that automaticaly

Ok, i did that, but i still get weird reactions at bootup. I chose my kernel from my bootloader, and it looks as if it's booting up, but it stops after giving me some CPU data, and the last line is something about using a certain version type for something. Here is my configuration, am i doing anything wrong?

In folder /boot
evilkernel (bzImage i think)
system.map-evilkernel

in the grub.conf file, i added at the bottom:

Code:

Title=evilkernel
root=&#40;hd0,1&#41;
kernel /evilkernel root=/dev/hda4

Does that look right?
