Problems solved by technology

However, the spare BIOS stored in the mainboard is a spare part that is not used at ordinary times. Users need to purchase two RAMs for storing the BIOS when purchasing this kind of mainboard. waste on
In addition, the traditional memory for storing spare basic input and output systems is embedded in the main board, and the parts need to be manually disassembled and soldered during maintenance, which increases the difficulty of maintenance and the risk of maintenance failure

Embodiment Construction

[0019] Please refer to FIG. 1 , the external BIOS device of this embodiment is equipped with a backup BIOS, which is used to replace the computer system to perform the boot function when an error occurs in the original main BIOS. This embodiment includes an external memory module 110 for storing a backup BIOS. And includes a motherboard pin interface 130 , which is embedded in the motherboard of the computer system and provides several pins for reading the external memory module 110 . In addition, a set of connection modules 120 are included for connecting the external memory module 110 to the motherboard pin interface 130 .

[0020] Please continue to refer to FIG. 1 , the external memory module 110 also includes a memory 112 and a connection connector 114 . The memory 112 adopts flash memory to store the above-mentioned standby BIOS. If necessary, the memory 112 can also use other types of memory. The connection connector 114 is used to connect the memory 112 and the conn...

Abstract

The invention discloses an externally connecting device with a basic input and output system, and relates to a basic input and output system equipment with restoration and backup functions; the invention is used for solving the problem of high cost and inconvenient maintenance existing in the present main-board with spare basic input and output system. The external device with a basic input and output system of the invention comprises an external memory module and a main-board pin interface, wherein, the spare basic input and output system data is stored in the external memory module. When the main basic input and output system data of the main-board is damaged to fail the starting up of the computer, the external spare basic input and output system equipment can take the place of the main basic input and output system equipment to start up, and can restore the data that leads the main basic input and output system to be damaged. The spare equipment of the invention is externally connected only when the main basic input and output system goes wrong, so as to lower the manufacturing and purchase cost of the main-board, while at the same time the invention has a lot of advantages of the traditional dual BIOS.

Description

technical field [0001] The invention relates to a backup device of an external basic input-output system, in particular to a basic input-output system device with repair and backup functions. Background technique [0002] The Basic Input Output System (BIOS) is firmware stored in the ROM of the motherboard. Its main function is to check whether the computer hardware and various peripheral devices are normal when starting up, and initialize various hardware to ensure the normal operation of the system. When we turn on the computer system, the central processing unit inside the computer will obtain the program from the basic input and output system to perform self-test at startup, then load the operating system, and hand over the control of the computer system to the operating system to complete the booting action. [0003] System manufacturers will write the normal basic input and output system data of the mainboard into the read-only memory before the mainboard leaves the f...
