Need Suggestions

[hech]

Please suggest cheap/commodity($50-$75) motherboards with socket 1155 that has LAN on Motherboard that works with iPXE perfectly Out-of-Box.

We will be using Windows 8 or Windows Server 2012.

ASRock, Gigabyte, MSI, Intel, ECS, etc... Any brand would do, I just need this to work smoothly.

I have tried:
ASRock H61M-VG4 with Realtek RTL8111/8168
Failed. MAC becomes 00:00:00:00:00:00. Long loading time followed by blue screen then reboot.

Intel DH61BF with Realtek RTL8111/8168
Failed. MAC becomes 00:00:00:00:00:00. Long loading time followed by blue screen then reboot.

Intel DH61WW with Intel 82579V
Failed. Bus-id becomes 82579LM. Long loading time followed by blue screen then reboot.

Compaq CQ40 with Realtek LAN on MoBo
Failed. Long loading time followed by blue screen then reboot.

Tried chainloading undionly.kpxe; ipxe.pxe, ipxe.kpxe, ipxe.kkpxe with specific drivers for each LAN on Motherboard. Also tried bootable .iso.

All boards install perfectly using wimboot/WinPE method but fails to boot(sometimes they boot, most times they don't).

Using Windows Server 2012, MS DHCP, MS iSCSI Target, IIS8, and Solarwinds TFTP for server.

Code:

#!ipxe

:retry
dhcp || goto retry
set initiator-iqn iqn.2010-04.org.ipxe:computenode
set keep-san 1
set netX/gateway 0.0.0.0
