to be filled by o.e.m

Hi

Can someone please confirm if ESXi only discovers FRU information during install?

I have an asrock server motherboard that didn't have any FRU information populted, I have since installed ESXi 5.5 and populated all the FRU fields but vshpere still reports back "to be filled by o.e.m"

Is there a command I can run to re-poll the FRU fields?

Thanks in advance.
