Description
Technical field
The invention relates to a kind of protection BIOS method for updating, particularly interrupt system and method thereof that BIOS upgrades about a kind of pushing power switch of avoiding.
Background technology
Along with scientific and technical information is showing improvement or progress day by day, computing machine becomes indispensable sci-tech product in the life already, also is important data acquisition media.Therefore computer system is also along with the increase of user's demand, the function of computer hardware also is improved, as change that central arithmetic processor, storer, hard disk and video card or the like are peripheral to be equipped with, the upgrading that this periphery is equipped with can be divided into two kinds, and a kind of is the product that directly changes new design, new technology into; Another kind then is with original BIOS (BasicInput/Output System) ROM and firmware (fireware) updating content, and for the user, upgrading BIOS is the most economical labour-saving method.But because when upgrading BIOS, if supply power breakdown, can cause upgrading the data transformation in the BIOS storer, when start next time can't normal boot-strap with enable computer hardware, yet power breakdown has many reasons, the power switch of the reason person of the being to use false touch machine shell panel of normal generation wherein, cause the host power supply start-up circuit to switch to powered-down, power supply is directly cut off, cause the failure of BIOS memory updating.
See also Fig. 1, it is a power initiation method flow diagram before existing BIOS upgrades.As shown in the figure, push when sending starting-up signal by power control switch 11, send the unlatching of an electric power starting signal triggering power circuit 13 via switch control chip 12, and send a low-potential signal to power supply unit 15, start this power supply unit 15 by power circuit 13.If this power control switch 11 of false touch this moment then can be sent closing of this power circuit 13 of power-off signal triggering by this switch control chip 12, and send a high potential signal to this power supply unit 15 by this power circuit 13, close this power supply unit 15; When carrying out the BIOS renewal, can cause BIOS to upgrade failure can't start shooting.
Therefore how can not cause upgrading failure because of the error shock source switch when upgrading the BIOS storer can't start shooting, and is a problem demanding prompt solution.
For avoiding the generation of the problems referred to above, the technology of the two BIOS systems of generation of manufacturer is arranged, adopt the BIOS accumulator system of a main pair, just tolerable upgrades and fails once, if when upgrading failure, then enables the BIOS storer of redundant.Yet the disruption that this technology and unresolved false touch switching on and shutting down button cause is only enabled backup of memory and is its remedial measure after failure, and must increase a ROM more, makes its system design more complicated, has increased cost of manufacture relatively.
Therefore, how providing a kind of when the BIOS memory for updating data, can not upgrade the system and the method thereof of failure because of the error shock source switch causes BIOS, is present problem demanding prompt solution.
Summary of the invention
