We have Domino 6.5 installed on Linux 2.1 AS.(Kernel 2.4.9-smp)

Now I installed another kernel which 2.4.19.

I compiled kernel 2.4.19 using following steps
linux-2.4.19$make oldconfig
linux-2.4.19$make clean - make bzImage - make modules - make modules_install
then copied arch/i386/boot/bzImage to /boot as vmlinuz-2.4.19
then made changes in lilo.conf

But when i am trying to boot from any one of this kernel I am getting following errors and then it stops there.

'ds:no socket drivers loaded'
'kmod:failed to exec /sbin/modprob -s -k block-major-8 , error =2'
'VFS:cannot open root device"803" or 08:03'
'Please appen a correct "root=" boot option'
'kernel panic : VFS :unable to mount root fs on 08:03'

**** my LILO.conf looks like this

prompt
timeout=50
default=linux
boot=/dev/sda
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear

image=/boot/vmlinuz-2.4.9-e.3smp

initrd=/boot/initrd-2.4.9-e.3smp.img

read-only
root=/dev/sda3

image=/boot/vmlinuz-2.4.19
label=linux-2.4.19

Pls guide me to come out from this problem.

Thanks in advance
