I wanted to try out PXE booting on my Pi3, but it seems I killed it.
I followed the "tutorial" here and copied start.elf and bootcode.bin onto the boot partition and added the config.txt line.
Rebooting the pi yielded no spash screen and only a solid green activity LED.
So I put the formerly working files back onto the SD card, but i still only get a solid green activity LED.
Removing the SD card yields no activity LED and also no link on the LAN.
I did reboot said Pi multiple times today already, so I know it worked.
I have and had nothing connected to the GPIOs.
