        Looking at the output of your kernel as it's loading, you have grub
working just fine.
The problem is with the kernel you've compiled...the line 
""request module[block-major-104]: Root fs not mounted""
typically means that you don't have the a specific option compiled in
the kernel...in your case, it's ciss...
is it compiled in as a module? 
And if you are doing your own kernel, then you should either do your own
initrd image OR just not use an initrd image.

Hello GNU team,

I  have had a look at the GRUB FAQ, also stepped through

I had no problems compiling the new kernel (had to make changes to fs.h
limits.h). Excellent documentation 'cept when you come to the specifics

NB: /etc/grub is a symbolic link to /boot/grub/grub.conf

Here is my /etc/grub.conf file contents...

password --md5********************
title Red Hat Linux (2.4.7-10)
root (hd0,0)
kernel /vmlinuz-2.4.7-10 ro root=/dev/cciss/c0d0p8
initrd /initrd-2.4.7-10.img

Now, by editing (hit e on Grub screen) after entering grub password, I
manually edit (as per instruction from Red Hat 7.2 manuals online). By
hitting e on the highlighted (2.4.7-10) I could see the following...

root (hd0,0)
kernel /vmlinuz-2.4.7-10 ro root=/dev/cciss/c0d0p8
initrd /initrd-2.4.7-10.img

I then edited the middle line to point to the new kernel (which I had
after successful compile) from
/usr/src/linux-2.4.7-10/arch/i386/boot/bzImage to /boot/bzImage.02102002

kernel /bzImage.02102002 ro root=/dev/cciss/c0d0p8

Then, as instructed, I hit b (for boot). On boot up I received the

NET4: Unix doamin sockets 1.0/SMP for Linux NET4.0.
ds: no socket drivers loaded!
request module[block-major-104]: Root fs not mounted
VFS: Cannot open root device "cciss/c0d0p8 or 68:08
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 68:08
