More Information
Summary:The invention discloses a BIOS data interaction method and device and a medium, and the method comprises the steps that a BIOS sends a data reading instruction to a BMC, the BMC stores data in a preset memory storage area of the BMC, and the storage space of the preset memory storage area is smaller than the video memory storage space of the BMC. And the BIOS judges whether data exist in the preset memory storage area or not, and if yes, the data are read through the PCIE transmission channel. According to the technical scheme, the BMC can quickly store the data in the preset memory storage area of the BMC in a memory mode, the BIOS directly reads the data in the preset memory storage area through the PCIE high-speed transmission channel, the low efficiency of transmitting the data through an LPC bus is avoided, in addition, the data is read from the preset memory storage area of the BMC, and the data transmission efficiency is improved. And the time for data interaction after the BIOS sends the request and w
