The option description:
This information option displays current pressure of a line +2.5 In, worked out by the motherboard stabilizator. At serviceable components (first of all it is a question immediately of the motherboard and about the power unit) displayed value should be close to reference 2.5 Century
At some implementations BIOS there is a color selection of the deduced information. If pressure within norm, you see dark blue digits if it quitted for admissible limits, color of digits will be replaced with the red. It is quite often possible to refuse control of the given pressure generally. For this purpose it is enough to select for an option value [Disabled] or [Ignore] (truth, the special sense in it is not present).
Be not surprised to constant "races" of displayed value — accuracy of circuits of measurement of the motherboard far from an ideal affects. At the serviceable motherboard and the power unit stability of all pressure is at rather high level, to be convinced of it it is possible, connecting any normal measuring instrument (the voltmeter or an oscillograph).
