Persistent Grub Configuration?

Hi all,

I installed UCS 5.0-10 on my used Primary 1330M3 with CP400i. Unfortunately it didn’t boot again after installation until I put some extra parameters into the grub config file and ran the grub config procedure. Everything is fine for now but I am afraid that a UCS update may revert my precious settings and bomb the reboot. Any ideas how to avoid that ?
