initial ram file system

[al_meh at encs.concordia.ca]

Hi

I installed the kernel-2.6.34 on the desktop ubuntu 10.4.
The problem is that I can not see the new kernel at time of boot. So I  
used the command:

mkinitramfs -o /boot/initrd.img-2.6.34 2.6.34

but still I can not see the new kernel installed

I appreciate if some one help me

Best
Ali
