The option description:
This information option displays current pressure of a line +12 In the power unit. At serviceable components (first of all it is a question directly of the power unit) the displayed size should be close to reference 12 Century
At some realisations BIOS there is a colour allocation of the deduced information. If pressure within norm, you see dark blue figures if it left for admissible limits, colour of figures will be replaced with the red. It is quite often possible to refuse control of the given pressure in general. For this purpose it is enough to choose for an option value [Disabled] or [Ignore] (truth, the special sense in it is not present).
Be not surprised to constant "jumps" of displayed value — accuracy of schemes of measurement of the motherboard far from an ideal affects. At the serviceable power unit stability of all pressure is at rather high level, to be convinced of it it is possible, having connected any normal measuring device (the voltmeter or an oscillograph).
