Grub & error trying to boot other linux partition

My 40 gig hard drive is partitioned like this

hda1 = Arch Linux partition (XFS file system, Grub installed to MBR)
hda5 = swap partition for Arch

hda6 = Vector Linux partiton (Reiser file system, LILO installed to superblock)
hda7 = swap partition for Vector

Here is my Grub menu.1st

menu.lst            [B---] 51 L:[  1+40  41/ 41] *(1251/1251b)= <EOF>
# Config file for GRUB - The GNU GRand Unified Bootloader
# /boot/grub/menu.lst

# (1) Vector Linux
title Vector Linux  [/boot/vmlinuz]
root   (hd0,5)
kernel /boot/vmlinuz root=/dev/discs/disc0/part6 ro

The problem is I can't get Vector to boot. The "Uncompressing Linux" message is follwed by all the usual messages and then at the end thses lines pop up.

VFS: cannot open root device "discs/disc0/part6" or 00:00
please append a correct "root=" boot option
Kernel panic:VFS: unable to mount fs on 00:00

I have tried changing the grub parameters to try .../part7 and ....part5 but part7 should be the swap so that won't work naturally.

Both had1 and hda6 are set as bootable btw.

Can I get some insight as to what I am doing wrong???

Re: Grub & error trying to boot other linux partition

Have you tried?
# (1) Vector Linux
title Vector Linux [/boot/vmlinuz]
root (hd0,5)
kernel /boot/vmlinuz root=/dev/hda6 ro

Not really sure if it will work but something I woudl try.

Re: Grub & error trying to boot other linux partition

That works!!

I must have been confused with the Grub/Lilo differences. Thanks a million for the answer!!

Re: Grub & error trying to boot other linux partition

No problem.  I am glad I was able to help. 

FYI,  In the grub entry for Vector you used the devfs (Arch) style (/dev/discs/disc0/partx) to define the root partition instead of the older dev system (/dev/hdax) that Vector expected.  Besides that there was nothing wrong with your grub entries.
