When UEFI PXE booting ASUS UN62 it boots but is stuck at Getting cached packet right after downloading NDP file? Anything I can do to get it to boot UEFI?
I would try change the pxe efi modes from syslinux to ipxe
Also make sure your kernel matches your efi architecture, It it's a 64 bit efi machine you must assign the 64bit kernel.
That is what I did, changed all to ipxe and working good now, Thanks!
