Embodiment
Be below, by specific embodiment, embodiments of the present invention are described, those skilled in the art can understand other advantage of the present invention and effect easily by content disclosed in the present specification.The present invention is also implemented by other different embodiment or is applied, and the every details in this instructions also can based on different viewpoints and application, carries out various modification and change not deviating under spirit of the present invention.
Refer to Fig. 1, show the operational flowchart forbidding the method for add-on card option read-only memory in BIOS of the present invention.In present embodiment, of the present inventionly in BIOS, forbid that the operational flowchart of the method for add-on card option read-only memory is applied in the computing machine with Basic Input or Output System (BIOS) (BIOS), to improve this opening computer self-inspection speed, this computing machine have for grafting respectively this add-on card multiple slots, be inserted in the add-on card of these slots described respectively, these add-on card described have option read-only memory respectively.Below namely the present invention is forbidden that in BIOS the concrete operation step of add-on card option read-only memory method is described in detail.
First step S100 is performed, one BIOS storer is provided, in this BIOS storer, define an address space, to set up an option read-only memory instruction list in this address space, this option read-only memory instruction list stores the inhibit command of corresponding respectively this add-on card option read-only memory.Then, step S110 is carried out.
In step s 110, (such as: CMOS random memory (CMOS RAM), and in this CMOS memory, store at least one CMOS numerical value, this CMOS numerical value may be the first different states or the second state to provide a CMOS memory.Then, step S120 is carried out.
In the step s 120, start this computing machine and perform startup self-detection program (POST), being read the CMOS numerical value stored in this CMOS memory by the BIOS of this computing machine.Then, step S130 is carried out.
In step s 130, which, judge whether the CMOS numerical value read is the first state, if so, then proceeds to step S140; If not, represent that this CMOS numerical value is the second state, then terminate the method.
In step S140, this BIOS calls the inhibit command of corresponding respectively this add-on card option read-only memory in this option read-only memory instruction list, to forbid the option read-only memory of respectively this add-on card, spend in save the startup self-detection program execute phase time of option read-only memory loading add-on card, thus correspondingly to increase work efficiency.
In another embodiment of the present invention, this option read-only memory instruction list also can store the enable command of corresponding respectively this add-on card option read-only memory, with in this startup self-detection program the term of execution, when detecting that this CMOS numerical value is the second state, this BIOS calls the enable command of corresponding respectively this add-on card option read-only memory in this option read-only memory instruction list, the option read-only memory of the add-on card plugged to make the subject of knowledge and the object of knowledge.
Preferably, this computing machine also can comprise a South Bridge chip, and this South Bridge chip has a universal input output connecting pin, and the first state of this CMOS numerical value or the second state correspond respectively to the high and low level value of this universal input output connecting pin (GPIO).For example, when this pin is low level value, make this CMOS numerical value be the first state, when this pin is high value, make this CMOS numerical value be the second state.
In another embodiment of the present invention, the high and low level value of this universal input output connecting pin arranges via wire jumper (Jumper) mode, for example, this universal input output connecting pin makes to become high and low level value by jumper short circuit.
Preferably, this option read-only memory instruction list also stores the default slot configuration information (comprising the preset data transmission path information corresponding to respectively this add-on card) respectively corresponding to this add-on card, to detect respectively this slot in this startup self-detection program the term of execution, with obtain respectively this slot relative to the actual slot configuration information (comprising the actual data transfer routing information corresponding to respectively this add-on card) of each this add-on card, and judge that whether this default slot configuration information is consistent with this actual slot configuration information simultaneously, to confirm respectively whether this add-on card is electrically connected corresponding slot further, namely actual slot configuration information comprises the information whether respectively this add-on card and corresponding slot are electrically connected further, find that respectively this add-on card is not electrically connected corresponding slot at present if detect, then may there are following two kinds of situations: (1) slot not yet sends power supply signal to corresponding add-on card, namely the voltage of the power supply unit supply of computing machine is not yet supplied to corresponding add-on card via this slot, (2) slot is not yet to corresponding add-on card tranmitting data register (frequency) signal, that is slot and corresponding add-on card do not have data communication relation.
Preferably, this actual slot configuration information comprises the current state information of described add-on card further, and when this BIOS detects that this current state information is invalid, this slot does not send a power supply signal or a clock signal to this add-on card of correspondence.
As mentioned above, the option read-only memory disposal route of add-on card of the present invention, provide effective computer booting self-inspection speed accelerated method, and then avoid in prior art because multiple add-on card with option read-only memory is inserted on each slot of motherboard simultaneously, cause in startup self-detection process and need to load aforementioned options read-only memory, cause expending and the problem of work efficiency degradation of too much time.
Above-mentioned embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any those skilled in the art all without prejudice under spirit of the present invention and category, can carry out modifying to above-mentioned embodiment and change.Therefore, the scope of the present invention, should listed by the protection domain of claims.
