Iam using Redhat linux 2.4.18-14(which came with
installing RHlinux-8.0.
Now I want to reconfigure the kernel.
I have download the linux 2.4.18 from ftp:kernel.org
Ihave put the file in /home/cs0205/
There itself I unzipped the file.
Then I saw a new directory /home/cs0205/linux
then cd /home/cs0205/linux
make mrproper
make xconfig
During the configuration I havn't made any changes
to
the default configuration.I have just saved the
default configuration and exited.
make dep
make clean
make bzImage
make modules
make modules_install
make install
After this I observed that there are new files in
/boot like vmlinuz-2.4.18 and vmlinuz-2.4.18.img
Before there were files named vmlinuz-2.4.18-14 and
vmlinuz-2.4.18-14.img
I have then changed my /etc/lilo.conf file as follows
prompt
timeout=50
default=linux_new
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear
image=/boot/vmlinuz-2.4.18-14
label=linux
initrd=/boot/initrd-2.4.18-14.img
read-only
append="hdb=ide-scsi root=LABEL=/"
image=/boot/vmlinuz-2.4.18
label=linux_new
initrd=/boot/initrd-2.4.18.img
read-only
append="hdb=ide-scsi root=LABEL=/"
other=/dev/hda1
optional
label=DOS
I have run /sbin/lilo
when I tried booting with the new kernel image, its
stopping after giving the message,
kernel panic:I have no root I want to scream
please help me!!!!!!!!!
Dear friends,
Iam new to linux.
I don't know why we should do make mrproper,dep
clean
bzImage,etc.
What is the result of this make?
will u please suggest any resources on net?
or any text book?
I have read somewhere saying that we have to copy
the
bzImage in linux/arch/boot/ to /boot/
I have also seen something regarding System.map!
What does this System.map and bzImage contain?
Do I really have to copy them?
Then what is the use of make install?
please answer to my queries!!!!!!
Thankyou!
for reading the mail patiently!

You should have, unless you have exactly the same configuration as Linus
Torvalds has.
Probably drivers for accessing the root filesystem are missing, but you
also need to configure a whole heap of other things as well.
The Kernel Howto at
http://www.linux.org/docs/ldp/howto/Kernel-HOWTO/
makes a good reading.
