BIOS serial port log: If the serial port log has been collected, you can query the
B/D/F information of the server by searching for the keyword "dumpiio".
UEFI Shell: You can obtain the B/D/F of the server using the pci command. Run
the help pci command to obtain the specific usage of the pci command.
