# Mappings for DMI/SMBIOS to Linux and dmidecode
Information can be put into dmi tables via some qemu-system hosts (x86_64 and aarch64).  That information is exposed in Linux under `/sys/class/dmi/id` and can be read with `dmidecode`.  The names are very annoyingly inconsistent.  The point of this doc is to map them.

## Mappings
Example qemu cmdline:

    qemu-system-x86_64 -smbios type=<type>,field=value[,...]
    
    qemu-system-x86_64 -smbios type=0,vendor=superco,version=1.2.3
