Thanks Simon!
I could find the scripts bootscc.sh and menu.lst.scc and made changes for
booting core 1-5 but there is another
problem I am facing. The bootscc.sh calls another script watchall.sh which
is being blocked due to access permissions.
Could you please let me know if watchall.sh is necessary for the
installation ? Also I could see the first command in watchall.sh as
"trap "pkill -P $$" SIGINT" whcih mught be getting blocked. Could you
please tell what is it supposed to do ?
I am just wondering if it can be made to execute without requiring root
