is there any option to update the BIOS of an APC-3100 via a remote connection? The help file says that you have to enter the UEFI BIOS and start the update from the shell. This requires a local access to the PC which is not wanted.
The Help is correct; I’m not aware of any way to update a BIOS remotely (unless by that you mean walking someone else through the procedure while you are not at the PC ). While you are interfacing with the BIOS, the main operating system is not running and there is no way to establish a remote connection.
BIOS updates do not need to happen very often unless you have older hardware or a newer update has features you need.
