98 | Getting your kernel config right is an iterative process that may require
|
---|
99 | that you recompile your kernel a couple of times. The simplest way to go
|
---|
100 | about it is to start by enabling modules and then compile everything that
|
---|
101 | may be needed by Lm Sensors as a module:
