New tables can be mapped to memory from binary file specified in "smbios_firmware" parameter of domain configuration. If particular table is absent in binary file, then it will not be mapped to memory. This method works for Windows domains as tables 7,8,9,26,27,28 are = not critical for OS boot and runtime. Also if "smbios_firmware" parameter is not provided, these tables will be skipped in write_smbios_tables function.
