Data interaction method of BMC and BIOS and related components

The invention discloses a BMC and BIOS data interaction method and related components, and the method comprises the steps: determining a sender sending a request and a channel for transmitting the request when the request is received; when it is determined that the sender is the BIOS and the channel is a KCS channel of a flash memory read-write service, BIOS boot data in the flash memory is stored in a data buffer area of the KCS channel, and the flash memory read-write service is different from the IPMI service. And sending a first signal to the BIOS through the KCS channel, so that the BIOS obtains BIOS startup data from a data buffer area of the KCS channel after receiving the first signal and stores the BIOS startup data in the DRAM. According to the method, the BMC provides a flash memory read-write service different from the IPMI service for the BIOS, the situation that the BIOS obtains the starting-up data slowly due to the fact that the IPMI service of the BMC is too busy, and the starting-up process
