I am trying to follow some instructions to update some firmware:
x64 UEFI environment:
- Boot to UEFI shell
- Run update.nsh
I don't know how to do this. When I boot do I have a choice to boot to UEFI Shell?
Do I need a separate bootable CD to go to UEFI shell or is this something like safe mode where I press a certain key to go to it?
