I can't boot Realtek ROM via iscsi on windows10 but intel card can do, Please discuss

[golfberserk]

Dear all,
Could anyone help me how to solved that?

First, My Ubuntu server 14.04.1 LTS uses iPXE 1.0.0+ for diskless on Windows 7 64 bits. No problem anything. I can boot diskless on LAN client such as REALTEK, ASTEROS, INTEL, MARVEL, Broadcom etc...

Anyhow, I want to boot diskless on Windows 10 64 bit on client.
My problem is (as I tested)
- Intel Pro 1000MT (from Lan card), Intel I217V can boot diskless win10
- REALTEK cannot boot to windows 10 logo.
It's hang and stay on page Boot from san 0x80 ... and not move (in spite of it's the same as Motherboard when I use windows 7)

Could anyone help me what problem on it and how to solve?

In my opinion, the problem come from iPXE version on my Ubuntu server. Is it correct?
