[Grml] grml2hd: initrd.img not found

[Hubert Gabler]

I installed grml 0.9 on a free partition and copied the essential lines
from grml /boot/grub/menu.lst to my standard menu.lst. It reads now:

title		Debian GNU/Linux, kernel 2.6.18-3-486
root		(hd0,2)
kernel		/boot/vmlinuz-2.6.18-3-486 root=/dev/sda3 vga=792 ro 
initrd		/boot/initrd.img-2.6.18-3-486
savedefault

title  		2.6.18-grml

kernel 		/boot/vmlinuz-2.6.18-grml root=/dev/hdd4 vga=0x0317
initrd 		/boot/initrd.img-2.6.18-grml
savedefault
# boot

title		Windows XP Home
root		(hd0,0)

Booting grml does not work because the system cannot find
initrd.img-2.6.18-grml. In fact it does not exist in grml's boot file.
Where does it hide ??

(I tried to use initrd.img -2.6.18-3-486, grml starts but I get a lot of
error messages)

Please give me a hint!
