<p>Sure Abner. We discussed the same earlier but I didnt follow up
with latest Redfish Host interface spec. <br>
</p>
<p>I will sync with him on this. <br>

After some conversations with OpenBMC people, I recognized RBC
daemon is standardized and Intel or IBM have their own
implementations to collaborate with RBC daemon.<br>

For the OEM ipmi commands defined for BIOS and bmc
communication, you probably can join Redfish Host Interface
meeting because we are defining the IPMI Redfish command in this
meeting. You may also reach out to John Leun from intel, who is
the representative of Intel for that meeting. <br>

I may have PR of the Remote Bios configuration document for
some cosmetic revises and make this spec more clear on system
firmware point of view.<br>

we are supporting Intel uses OEM IPMI command , IBM
uses PLDM method <br>
is transfer data from BIOS to the BMC.<br>
<br>
In Intel, we are using (Intel prop) XML format which
contain all needed <br>
info from BIOS to the BMC.<br>
<br>
Let me know whats requirement. we can discuss the same.<br>
<br>
This BIOS config -setting should be generic.<br>
<br>
<br>
Thanks<br>
