Settings change only when client rebooted

Hi!

I was messing around to test the Dell BIOS Provider module, and was trying to use it to configure the Wake On Lan on some Dell machines.

What I did was:

Create a script that changes the Wake On Lan and Deep Sleep Control settings under Power Management category on a remote computer.

Check those settings.

PS: The Windows network adapter configuration I'm doing manually for now

Then I turned off that machine and the network card wasn't ready to use.

So I have turned on the machine and checked inside the BIOS the settings and they were correct.

I turned of the machine again and the network card was ready...

My question is: Is a reboot necessary to apply every change we make using the module?
