/etc/init.d/rcS is default sysinit script that is run once the kernel is finished booting. /etc/init.d/rcS is called from init process as a last action (see init.c).
Error would suggest that you do not have the /etc/init.d/rcS in place.

Put /etc/init.d/rcS on your FS with this content:
#!/bin/sh
echo Exec $0 script..
exit $?

and make it executable. Upon boot this script should be run and message printed in the console. Of course for production /etc/init.d/rcS should do a bit more work..
