I received some errors with my new kernel(2.4.22) so I decided to try again. I read more from HOWTO. I observed that after decompressing the 2.4.22 kernel there is no .config file so I had copied the .config file from the /boot (this was the .config file of the 2.4.20 kernel) into the /usr/src/linux-2.4.22 and after that
make dep
make bzImage
make modules
make modules_install
cd /sbin
./mkinitrd ./initrd-2.4.22.img 2.4.22
cp /usr/src/linux-2.4.22/arch/i386/boot/bzImage /boot/vmlinux-2.4.22
cp ./initrd-2.4.22.img /boot
cp /usr/src/linux-2.4.22/.config /boot/config-2.4.22
after that I configured GRUB but at start up I receive
Kernel panic: No init found; Try passing init= option to kernel.
What should I do now?
It is good that I copied the .config file of the distribution kernel to use it with this new kernel? Initially I tried with make oldconfig but I didn’t had a .config file in the /usr/src/linux-2.4.22 and it didn’t work write(for example the processor type remained Pentium III and I have am AMD Athlon XP)

Excuse my newbies!

what does your menu.lst (/boot/grub/menu.lst) look like?

In menu.lst I have the following:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,1)
# kernel /vmlinuz-version ro root=/dev/hda3
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,1)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-8)
root (hd0,1)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.20-8.img
title Red Hat Linux (2.4.22)

kernel /vmlinux-2.4.22 ro root=/dev/hda3
initrd /initrd-2.4.22.img

I fix the problem with the kernel and now it loads but I still have some problems:
USB mouse, keyboard…FAILED
Iptables…FAILED
What is iptables and how can I activate it from kernel(what do I have turn on?)?
I turned on the ntfs support but how can I mount the ntfs partition?
I have the following partitions:
1-ntfs
2-boot
3-ext3
4-swap
(I installed linux RedHat 9.0 after windows XP)

Excuse my newbiess

Perhaps you have not included USB and iptables support in the kernel. If you require them then they should either be included directly or as modules in the kernel. You would have to do the configure again and either include them or select them as modules then recompile the kernel and install it as before.

What did you do to fix the "Kernel panic: No init found. Try passing init= option to kernel" issue?

I have RH9 and I am required to upgrade to the 2.4.22 kernel.

I recompiled the kernel with ext3 into kernel and after that it was OK
