Abstract: A method for locating a fault of a server includes: physically connecting a GPIO pin of a BMC to a GPIO pin of target hardware in advance; reading a current state value of the GPIO signal of the target hardware in a power-on and activation process of a mainboard, and loading a corresponding version of the firmware according to the current state value and the condition for switching; and in response to determining that the corresponding version of the firmware is the debug version, outputting serial port log information of the debug version to the BMC, and in response to determining that the corresponding version of the firmware is the release version, determining whether to change the state value of the GPIO signal on a connection between the BMC and the target hardware according to a preset normal activation condition and a system event log.

Abstract: A method and an apparatus for data interaction between a BIOS and a BMC of a server, a device and a readable storage medium. According to the state of an IPMI link between a BIOS and a BMC, it is determined whether to perform data interaction. At the same time, whether the BMC cannot be activated due to abnormalities are determined by confirming whether the number of times of restarting the server reaches preset threshold at the BDS stage of the BIOS. When the number of times of restarting the server reaches the preset threshold and the BMC is still not activated, the BMC is determined to be abnormal. When the number of times of restarting the server has not yet reached preset threshold, the BIOS performs the action of restarting system, wherein preset threshold is confirmed by a variable self-defined inside the BIOS and may be set freely.

Abstract: A method for supporting TCM communication by a BIOS of an ARM server, including: setting an access mode of a LPC bus device to a 4-byte mode by means of a BIOS of an ARM server; causing the BIOS to perform data communication with a TCM chip of the LPC bus device in the 4-byte mode; in response to the BIOS reading a register by means of the LPC bus device, determining a type of the register; in response to determining that the type of the register is a specific FIFO register, changing a control register from the 4-byte mode to a single-byte mode, and performing single-byte read-write on the specific FIFO register; and in response to completion of read-write of the specific FIFO register, changing the control register to the 4-byte mode by means of the BIOS, and performing a read-write operation on other FIFO registers.

Abstract: A method, a device, an apparatus for identifying a graphics card of a GPU server, and a medium are provided. The method includes: obtaining correlation information of a graphics card captured by an operation of enumerating PCI devices during a startup process of running a BIOS; determining whether the graphics card belongs to a preset category; reading a memory address of the graphics card in a configuration space of the PCI device in a case that the graphics card belongs to the preset category, and obtaining an actual memory address based on the memory address and an offset; and resetting the graphics card based on the actual memory address, and sending a restart instruction to perform a restart operation.

Abstract: A method, a device and a medium for allocating a resource based on a type of a PCI device are provided. In a case of running a BIOS program during a start-up process, information of a Switch chip captured by a PCI enumeration operation is acquired. It is determined whether the PCI device is connected to a GPU server based on the information of the Switch chip. An operation of allocating the PCI device with an IO resource is cancelled in a case that the PCI device is connected to the GPU server, and the PCI device is allocated with an IO resource and a memory resource based on a preset allocation rule in a case that the PCI device is not connected to the GPU server.
