The Linux boot process will first mount an initial ramdisk to mount the harddisks. This is how you modify an initrd:

mkdir tmp
cd tmp
cp /boot/initrd initrd.gz
gunzip initrd.gz
mkdir tmp2
cd tmp2
cpio -id < ../initrd 

Do the needed changes now in this folder. Then pack the initrd again:

find . | cpio --create --format='newc' > ../newinitrd
cd ..
gzip newinitrd

Your new initrd is now called newinitrd.gz.
