Abstract
The invention provides server system based double-BIOS (basic input/output system) design. According to the server system based double-BIOS design, an SPI bus of a system PCH is connected to a switch chip of 1-to-2, the switch chip connects the SPI bus to a primary BIOS chip and a secondary BIOS chip respectively, and a logic control unit controls the SPI bus of the PCH to be connected to the primary BIOS chip and the secondary BIOS chip. In a default state, the SPI bus of the PCH is connected to the primary BIOS chip; when the primary BIOS chip breaks down, the logic control unit switches the SPI bus of the PCH to the secondary BIOS chip through the switch chip to guarantee function normality of a BIOS. Compared with the prior art, the server system based double-BIOS design has the advantages that BIOS redundancy can be realized, system reliability can be improved, and faults such as starting failure of a system due to damage to the BIOS can be avoided; moreover, reasonable design, simple structure, easiness in processing, convenience in use and the like are realized, so that the server system based double-BIOS design has high application value.
Description
Technical field
The present invention relates to server system technical field, specifically a kind of two BIOS designs based on server system.
Background technology
The reliability requirement of development to server of server technology is more and more higher now, and BIOS is as a part extremely important in system, self-evident on the impact of whole system, ensures the reliability and stability of BIOS, for of crucial importance system.The present invention is directed to this situation, by increasing BIOS redundancy, to ensure the security of BIOS.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of two BIOS designs based on server system are provided.
Technical scheme of the present invention realizes in the following manner, the spi bus of system PCH is connected to the switch chip of 1-to-2 by its structure, spi bus is connected respectively to principal and subordinate's two BIOS chips by switch chip, is connected to principal and subordinate BIOS chip by the spi bus of logic control element control PCH.Under default conditions, the spi bus of PCH is connected to main BIOS chip, and when main BIOS chip breaks down, the spi bus of PCH is switched to from BIOS by switch chip by logic control element, ensures that BIOS function is normal.
Advantage of the present invention is:
A kind of two BIOS designs based on server system of the present invention compared to the prior art, BIOS redundancy can be realized, improve system reliability, avoid occurring occurring that system such as cannot to be started shooting at the fault because BIOS damages, and the present invention have reasonable in design, structure simple, be easy to processing, the feature such as easy to use, thus, there is good use value.
Embodiment
Below a kind of two BIOS designs based on server system of the present invention are described in detail below.
A kind of two BIOS designs based on server system of the present invention, the spi bus of system PCH is connected to the switch chip of 1-to-2, spi bus is connected respectively to principal and subordinate's two BIOS chips by switch chip, is connected to principal and subordinate BIOS chip by the spi bus of logic control element control PCH.Under default conditions, the spi bus of PCH is connected to main BIOS chip, and when main BIOS chip breaks down, the spi bus of PCH is switched to from BIOS by switch chip by logic control element, ensures that BIOS function is normal.
The spi bus of PCH is connected to the first port of switch chip, the second port of switch chip is connected to Main BIOS, the 3rd port is connected to 2nd BIOS.By default, switch chip first port is connected with the second port by logic control element by system, and the spi bus of PCH is connected to Main BIOS, and now Main BIOS can use, and system can normally work.
When Main BIOS breaks down, upgrade unsuccessfully etc. situation time, switch chip first port is connected with the second port by logic control element by system, the spi bus of PCH is connected to 2nd BIOS, and now 2nd BIOS can use, and system can normally work.
It is very simple and convenient that a kind of two BIOS based on server system of the present invention design its processing and fabricating, can process to specifications.
Except the technical characteristic described in instructions, be the known technology of those skilled in the art.
Claims (1)
1. the two BIOS designs based on server system, it is characterized in that the spi bus by system PCH is connected to the switch chip of 1-to-2, spi bus is connected respectively to principal and subordinate's two BIOS chips by switch chip, is connected to principal and subordinate BIOS chip by the spi bus of logic control element control PCH; Under default conditions, the spi bus of PCH is connected to main BIOS chip, and when main BIOS chip breaks down, the spi bus of PCH is switched to from BIOS by switch chip by logic control element, ensures that BIOS function is normal.
