I tried to use the iPXE /usr/share/ipxe/ipxe-x86_64.efi, but it had some
issues with the network card, iirc, I think I saw the network interface
down, though it likely uses a wrong driver?
Still, the newer 6.04 one did work, except for loading the large initrd
file (which took more than 1 minute, which may be the reason it times
out?), which is probably not UEFI related?
