Hi

Can anyone show me how to make a new initrd for a newly rolled kernel? I 
have to install a 'custom' 2.6.14 kernel and i have build the kernel and 
now just trying to build the initrd

cd /boot
mkinitrd initrd-2.6.14.img 2.6.14
No module mptbase found for kernel 2.6.14, aborting.

What am i doing wrong?

thanks
