Re: help on frame buffer

Thanks for the reply.

I downloaded the latest kernel  2.6.11.11  and I followed the same step 
with 
make modules
and
make modules_install
then I did 

 mkinitrd  /boot/initrd-2.6.11.2k5.img    2.6.11.2k5

the lilo.conf file is

----------------------------------------------------------
prompt
timeout=50
default=DOS
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
message=/boot/message
lba32

image=/boot/vmlinuz-2.6.11.2k5
        label=2.6.11.2k5
        initrd=/boot/initrd-2.6.11.2k5.img
        read-only
        append="root=LABEL=/"

image=/boot/vmlinuz-2.4.20-8
        label=linux
        initrd=/boot/initrd-2.4.20-8.img
        read-only
        append="root=LABEL=/"

other=/dev/hda1
        optional
        label=DOS
-----------------------------------------------------------

now I did 
lilo -v

after rebooting, I am getting the following error

mount: error 19 mounting ext3
pivotroot: pivot_root (/sysroot, /initrd) failed: 2
umount   /initrd  /proc failed :2
kernel panic - not syncing : no init found, try passing "init = option" to 
kernel

what would be the error in this ?

    Maybe you need to do
           make modules
           make modules_install
It looks like you don't have an initrd=... line in lilo.conf for your
previous kernel, but if you do, you should make one for this kernel.
