menu.lst config for dual knoppix hdd/gentoo

Previously installed knoppix on HD. No problem
Installed Gentoo . Gentoo works fine but no longer able to boot knoppix.
All my attempts to edit menu.lst fail.
I do not seem to be able to specify which dev the real_root is on after the kernel is loaded.


initial hdd installation of knoppix lilo and fstab

boot=/dev/hda
root=.dev/hda1
image=/boot/vmlinuz-2.6.6
label = "linux"
initrd=/boot/initrd.img-2.6.6
append="ramdisk_size=100000 init=/etc/init

fstab (abridged by me)
/dev/hda1 / ext3 defaults,error=ro 0 1
#added by knoppix
/dev/hda2 /mnt/hda2 ext3 noauto 0 0
#added by knoppix
/dev/hda3 none swap defaults 0 0



after the gentoo install grub menu.lst is

grub
def 0
timeout 30
title gentoo
root (hd0.0)
kernel /boot/kernel<arch>
root=/dev/ram0
init=/linuxrc
intrd /boot/initramfs-gentoo

fstab
/dev/hda2 none swap sw 0 0
/dev/hda5 none swap
/dev/hda6 / ext defaults
non /proc proc defaults
non /dev/shm tmpfs default


Ok. The problem not too clearly seen by me is:
I repartitioned the drive. Gentoo is on hda5/6
I think the knoppix swap is hda2
grub (hd0,00) seems to be where root originates prior to kernel loading; where real_root should be eludes me.
But then I am feeling a touch stupid at this point and hope the obvious is apparent to someone else.


the last edit I tried was (preceded by every variation I could think of)
title knoppix
root (hd0.0)
kernel(hd0,0)/boot/vmlinuz-2.6.6
ramdisk_size=100000 init=/etc/init
initrd(hd0,0)/boot/vmlinuz-2.6.6

no matter what I then list as root=
/dev/hda1 or /dev/ram0

or anything else, the error codes 11, 15 or kernel panic occur. Unknown device or string, unrecognised string

Can anyone a. critique the menu.lst script above
b.tell me where the real_root should be?

thanks
