Boot to ISO Methods Comparison

Using Remote Update

Remote update, also known as out-of-band update or operating system-

independent platform update, allows you to update the system independent

of the state of the operating system. You can initiate the firmware update

regardless of the system power on or off state.

Benefits of Remote Update

With Operating System independent platform update, an operating system

need not be running on the system. Multiple updates can be scheduled

together along with a graceful or power-cycle reboot into UEFI system
