Boot into Visual BIOS (F2)
Select the Wrench menu (upper right), select Visual Bios Settings
Disable Internet Updates (Requires a mouse due to the wonders of Visual BIOS)
Select Advanced tab then Boot
Disable Legacy Boot (under the Legacy Boot Priority pane on the right)
Select the Boot Configuration tab in the left pane
Enable “Boot USB Devices First”, “Boot Network Devices Last”, and “Unlimited Boot to Network Attempts”
Make sure USB Legacy Support in the “Devices” section is Disabled

Build Zircon for x86-64
The bootloader is here: build-zircon-pc-x86-64/bootloader/bootx64.efi
Copy bootx64.efi to /EFI/BOOT/BOOTX64.EFI on the USB flash drive.
Use this flash drive to network boot.
If you copy zircon.bin to /zircon.bin on the flash drive it will boot from the flash drive instead of the network.
