Embodiment
Below be through specific embodiment embodiment of the present invention to be described, those skilled in the art can understand other advantage of the present invention and effect easily by the content that this instructions disclosed.The present invention also can implement or use through other different embodiment, and each item details in this instructions also can be based on different viewpoints and application, carries out various modifications and change under the spirit of the present invention not deviating from.
See also Fig. 1, show the operational flowchart of in BIOS, forbidding the method for add-on card option read-only memory of the present invention.In this embodiment; In the operational flowchart of in BIOS, forbidding the method for add-on card option read-only memory of the present invention is applied to the to have Basic Input or Output System (BIOS) computing machine of (BIOS); To improve this opening computer self check speed; This computing machine has a plurality of slots of this add-on card respectively of supply pegging graft, is inserted in the add-on card of said these slots respectively, and said these add-on card have the option read-only memory respectively.Below promptly the present invention is forbidden that in BIOS the concrete operations step of add-on card option read-only memory method is elaborated.
Execution in step S100 at first; One BIOS storer is provided; Definition one address space in this BIOS storer, in this address space, to set up an option read-only memory instruction list, this option read-only memory instruction list stores the corresponding respectively inhibit command of this add-on card option read-only memory.Then, carry out step S110.
In step S110, provide a CMOS memory (for example: CMOS random memory (CMOS RAM), and in this CMOS memory the storage at least one CMOS numerical value, this CMOS numerical value possibly be the first different states or second state.Then, carry out step S120.
In step S120, start this computing machine and carry out startup self-detection program (POST), the BIOS through this computing machine reads the CMOS numerical value of being stored in this CMOS memory.Then, carry out step S130.
In step S130, judge whether the CMOS numerical value that is read is first state, if then proceed to step S140; If not, represent that this CMOS numerical value is second state, then finishes this method.
In step S140; This BIOS calls the corresponding respectively inhibit command of this add-on card option read-only memory in this option read-only memory instruction list; To forbid the respectively option read-only memory of this add-on card; Saving the time that the startup self-detection program execute phase spends in the option read-only memory that loads add-on card, thus corresponding increasing work efficiency.
In another embodiment of the present invention; This option read-only memory instruction list also can store the corresponding respectively enable command of this add-on card option read-only memory; With in this startup self-detection program the term of execution; When detecting this CMOS numerical value and be second state, this BIOS calls the corresponding respectively enable command of this add-on card option read-only memory in this option read-only memory instruction list, so that the option read-only memory of the add-on card that the subject of knowledge and the object of knowledge plugs.
Preferably, this computing machine also can comprise a South Bridge chip, and this South Bridge chip has a general input and output pin, and first state of this CMOS numerical value or second state correspond respectively to the high and low level value of this general input and output pin (GPIO).For example, when this pin is low level value, make that this CMOS numerical value is first state, when this pin is high value, make that this CMOS numerical value is second state.
In another embodiment of the present invention, the high and low level value of this general input and output pin is to be provided with via wire jumper (Jumper) mode, and for example, this general input and output pin can make through wire jumper mode short circuit becomes high and low level value.
Preferably; This option read-only memory instruction list also stores respectively the pairing preset slot configuration information of this add-on card (comprise corresponding to respectively the preset data transmission path information of this add-on card); To detect respectively this slot in this startup self-detection program the term of execution; To obtain respectively this slot with respect to the actual slot configuration information of this add-on card respectively (comprise corresponding to respectively the actual data transfer routing information of this add-on card); And judge simultaneously whether this preset slot configuration information is consistent with this actual slot configuration information; With further affirmation respectively this add-on card whether electrically connect pairing slot; Be that actual slot configuration information further comprises the information whether respectively this add-on card and pairing slot electrically connect; Find that respectively this add-on card does not electrically connect pairing slot at present if detect, following two kinds of situation then possibly take place: (1) slot does not send power supply signal to pairing add-on card as yet, and promptly the voltage of the power supply unit supply of computing machine does not offer pairing add-on card via this slot as yet; (2) slot is as yet to pairing add-on card tranmitting data register (frequency) signal, that is slot and pairing add-on card do not have the data connected relation.
Preferably, this actual slot configuration information further comprises the current state information of said add-on card, and as this BIOS when to detect this current status information be invalid, this slot does not send a power supply signal or a clock signal to this add-on card of correspondence.
As stated; The option read-only memory disposal route of add-on card of the present invention; Effective computer booting self check speed accelerated method is provided; And then avoid being inserted in simultaneously on each slot of motherboard because of a plurality of add-on card that have the option read-only memory in the prior art, causing needs in the startup self-detection process to load the aforementioned options read-only memory, causes expending and the serious problem that descends of work efficiency of too much time.
Above-mentioned embodiment is illustrative principle of the present invention and effect thereof only, but not is used to limit the present invention.Any those skilled in the art all can be under spirit of the present invention and category, and above-mentioned embodiment is modified and changed.Therefore, rights protection scope of the present invention should be listed like the protection domain of claims.
