System Management BIOS (SMBIOS) is a specification for how motherboard and system vendors present management information about their products in a standard format by extending the BIOS interface on Intel architecture systems. As of today the latest spec is 3.0 and can be downloaded from DMTF website. This commit adds a simple and minimum required implementation.
