Installed knx3.6 with lilo in partition

Installed centos-3 (an rhe rebuild) with grub in mbr

Grub sees both, but grub conf had to be diddled to see knx kernel and initrd.img

Grub indeed starts the knx boot, but quits with a kernel panic suggesting on stdout:
Code:
Kernel panic: No init found.  Try passing init= option to kernel
Here's the relevant bit from grub.conf:
Code:
title knoppix
   rootnoverify (hd0,1)
   kernel /boot/vmlinuz-2.4.27 ro root=/dev/hda1 nolapic acpi=on nodma init=5
   initrd /boot/initrd.img-2.4.27
That line for the kernel is a composite of an earlier answer about cheatcodes for knx3.6 on my laptop and a howto on dualbooting multiple linux distros. I'm guessing the trouble is the syntax on "init=5" but can't figure out where else to look. Many thanks!
