disable AHCI mode

[jccfonz]

Hi,

First of all thanks for your future answers/suggestions

I have an HP probook 440 G1 below some specs:

Current BIOS Version: L74 ver 01.08
Current BIOS release Date: 02/13/2014
Video BIOS revision: Intel 2175
Processor type: intel® core™ i3-4000m CPU
Procesor speed: 2.4 GHz

I want to enable/disable AHCI mode, the option is there but can`t modify it, what do you guys suggest?

Regards
