Hello Mani,
-Updating the BIOS will only update the ME firmware if it includes a change for the ME Firmware.
-You can get information on the methods available to perform Desktop boardBIOS updates
here.
-It is not possible to upgrade from one AMT major version to another because there are hardware requirements across AMT releases.
-Not sure what you mean by remote update of BIOS. If you take a look at the methods above you may see what you want. I'm thinking thatyou should be able to create a bundle that you send out like a patch that is executed on the OS of the client.
