This tries to add information about when each option was added. It goes back to version 183. The version info is included from a separate file to allow generating it, which would allow more control on the formatting of the final output.

<title>Description</title>
|
|
|
|
<para>Various OS components process SMBIOS Type 11 vendor strings that a virtual machine manager (VMM)
|
|
may set and a virtual machine (VM) receives. SMBIOS Type 11 vendor strings may play a similar role as
|
|
<citerefentry><refentrytitle>kernel-command-line</refentrytitle><manvolnum>1</manvolnum></citerefentry>
|
|
parameters but generally are under control of the VMM rather than the boot loader or UKI.</para>
|
|
|
|
<para>For details on SMBIOS Type 11 see the <ulink url="https://www.dmtf.org/standards/smbios/">System
