Cautioning that I am still having a few problems with my own 2.4.1 install...
You would probably be best off d/l'ing the 2.4.1 sources (say from
www.kernel.org), and then compiling them yourself (see the kernel HOWTO for
instructions). In brief, you would d/l the source tar.gz file. In your home
dir, create a src subdir and put the tar in it; cd into that dir. With
"tar zxpfv linux-2.4.1.tar.gz" as a sample command, the sources will untar
and be left in a linux subdir of your src subdir. You can then CD into that
dir, and do make config, make menuconfig, or make xconfig to configure the
kernel (the various choices do a text-based, text-menu based, or x based
configuration, respectively. I like xconfig myself).
Once the config is done, the sequence of commands:
make dep
make clean
make bzImage
make modules
will build your kernel and loadable modules.
As root, do make modules_install to install the new modules. Then, copy the
kernel image (assuming you are on a i386 architecture system, it is in
linux/arch/i386/boot/bzImage) to your /boot directory. Also copy System.map
from the linux dir to /boot. I generally name the bzImage something like
vmlinuz-2.4.1 (for kernel version 2.4.1) and the system map System.map-2.4.1
so as not to overwrite anything that I need in /boot, like the currently
(working) kernel. BE VERY CAREFUL NOT TO TRASH YOUR WORKING KERNEL AND SYSTEM
MAP, OR YOUR SYSTEM WILL NOT BE BOOTABLE!!!
If you are using grub, in the file /boot/grub/menu.lst you will find the
lines that specify kernels to load. Take the current one titled "linux", copy
it witha title of (for instance) linux-2.4.1 and clone as appropriate the
data in that section (this is likely to be obvious). Now reboot, and cross
your fingers....
Good luck.
