iPXE broken with B75M-GL / rtl8111e?

[netwerk]

Sorry, it took so long for my post to show up that I forgot I posted.

It turns out that it's the motherboard BIOS that is not working correctly. If I connect a hard drive (even with the SATA controller disabled) then it no longer spontaneously reboots and I can boot diskless. I have contacted ASRock and they are suppose to look at it though I don't have much hope but who knows.

iPXE is otherwise working great, thanks!
