for initrd.img

Under the /boot directory, the kernel file must be bzImage or
vmlinuz-version. And one of most important file is initrd.img.
The initrd.img contains all the modules (driver). The kernel
loads initrd.img to RAM as RAM drive. Hence, when booting up
a linux, all the device, that are modules-enabled, will be ready 
for use.

try "man mkinitrd" for details.
