Abstract

The invention provides a double-flash mainboard, electronic equipment applying the same and a design method of the double-flash mainboard, the double-flash mainboard comprises a programmable logic device, the mainboard further comprises a master flash and a slave flash, the master flash is provided with a first BIOS mirror image and a first BMC mirror image, and the slave flash is provided with a second BIOS mirror image and a second BMC mirror image; and the programmable logic device is used for gating of the master flash and the slave flash. According to the invention, the main flash and the slave flash are arranged on the mainboard, and each flash is provided with the BIOS mirror image and the BMC mirror image, so that the requirement of double flashes of devices on the mainboard is met, the requirement can be realized by arranging only two flashes on the mainboard, and the number of the devices on the mainboard is reduced; in addition, the gating function of the master flash and the slave flash is integrated into the programmable logic device, so that the number of devices on the mainboard is further reduced. The number of solid parts on the mainboard is reduced, the space of circuit layout is optimized, the wiring difficulty is reduced, and the placing elasticity of the parts is improved.

Description

technical field [0001] The invention relates to the technical field of server motherboard design, in particular to a dual-flash motherboard, electronic equipment using the same and a design method thereof. Background technique [0002] When designing the current motherboard, it is necessary to reserve dual flash (a type of memory device, which is a non-volatile memory) to deal with the situation that the system cannot operate normally due to flash damage. [0003] For the motherboard, such as figure 1 As shown, the objects that need to reserve dual flash devices include BIOS (Basic Input Output System, Basic Input Output System) and BMC (Baseboard Management Controller, Baseboard Management Controller), so four flash chips need to be set on one motherboard. And for the gate switching of the two flashes, a corresponding SPI (Serial Peripheral Interface, Serial Peripheral Interface) MUX (multiplexer, transfer switch) switcher is required to realize. [0004] In the design st...
