So it is a edk2 implementation, and can you point me at
the bhyve version of it?  The Qemu/KVM version is rather
not relavent to this discussion as that would not work due
to core vmm implementation differences.

Yes, I have been in Prague for 2 weeks and rather sleep
deprived while attending netdev and IETF/104.

We need to be careful in what one calls the "version"
when doing this.

  ^^^^^^^^^^^   This is the critical version, this is the
version of the SMBIOS/dmitables implemented by the bios.

Bhyve should be reporting a SMBios major 2 minor 6 (aka 2.6),
see usr.sbin/bhyve/smbiostbl.c function smbios_ep_initializer.

                          ^^^^^^ This is an arbitrary value
that a vendor sets.  We presently report 1.0 for the legacy bios
version string, see usr.sbin/bhyyve/smbiostbl.c smbios_type1_strings[]
