How to use
Please read How to use Semaphore JB guide for information about the features

In order to load various modules of the kernel and enable or disable features use Semaphore Manager or use HM.Carbide's Semaphore Script Manager application. It automatically copies and runs the respective scripts from /res/scripts to /system/etc/init.d directory.
Custom Voltage may be configured with Voltage control or similar applications.

For more information check the semaphore kernel website:

What device do you have?
What rom are you running?
I asked because your Tapatalk sig is for the I9000 but this kernel is for the vibrant.

I appreciate for all your hard work and I'm wondering if there is any option to turn on led notification. Please advise.
