Thank you for contacting Intel® technical support. I will be more than happy to help you.
I understand that you want to know if the Intel® Compute Cards in an Intel® Compute Card Dock will support network boot.
Yes, this option is supported. You just need to access the BIOS (press F2 during POST), go to Boot > Network Boot > UEFI PXE. Then save the settings and exit the BIOS, access the boot menu (press F10 during POST), and select the option that begins with "UEFI : LAN".
