I have a DELL machine that use Phoenix SecureCore Tiano as its UEFI/BIOS However, it is totally not configurable as its UEFI shell & menus are hidden in BIOS Setup.
I'm wondering if there were tools that can modify the UEFI settings(such as Boot Items) in user mode? such as "efibootmgr" in linux.
btw, because it is not configurable, I think the boot process is in legacy mode so that's to say OSes can not detect the UEFI exist, am i right?
so, that's the paradox: I must be boot in non-legacy mode to enable UEFI tools to modify boot items in user mode? but I must enable UEFI tools to modify boot items first to enable non-legacy boot?
