where's the netboot/diebian-installer kernel binary?

["johannes swoboda" <johannes.swoboda@gmail.com>]

good evening.
There's a capter into the installation guide how to boot the debian
installer with grub:
http://www.us.debian.org/releases/stable/i386/ch04s05.html.en#files-lilo
it says that I need
   * vmlinuz (kernel binary)
   *initrd.gz (ramdisk image).

I've found the ramdisk image:
ftp://ftp.debian.de/debian/dists/sarge/main/installer-i386/current/images/netboot/debian-installer/i386/
but; where "its corresponding kernel"?
