I try to make a custom firmware by Intel Firmware Engine.
First, I built .efi and .cap files by following this Intel video tutorial.
copy files to my USB drive and reboot
type in : CapsuleApp.efi FVMAIN.Cap
the system reboot, but show these message:
Updating the firmware......em memory tested OK
Capsule Request Cold Reboot.
Resetting system in 2 seconds...
"cold reboot" means unplug the power and plug in?
I tried, but it show the same message.
