HI.
I have a MacPro 5.1 (see details in my sig).
I am on Bootrom 140.0.0.0.0. But upgrading to a newer Bootrom does not work anymore.
Tried to press the button until the chime comes up -> does not work
Tried to press the button until the led blinks -> does not work
Tried to press the button 10s longer after the led blinks -> does not work
The screens stays black. If i press the power button after 30min, the MacPro shuts down.
What can i try to update my bootrom?
Thanks for your help.
Andreas
