However, after one reboot, iPXE fail at DHCP, and it won't even communicate with internet after setting a static IP.

However, booting a Linux live CD, so it connect the network card to the internet once, and then rebooting, then iPXE successfully DHCP ONCE again. After next reboot, same problem.

It seems like Windows 7 network driver "does" something with the network card so iPXE cannot use it, and the Linux live CD "resets" this state so its useable by iPXE again.

Does a full cold reset (i.e. removing the power cable) also clear the problem for a single boot?

Which NIC is present on your motherboard? You can find out using the commands "ifstat" (or "show chip") from within the iPXE shell.

If you know which iPXE driver is being used, then try adding an appropriate "DEBUG=" option to the iPXE build. For example, if your onboard NIC is a Realtek, try building a USB-bootable debug version of iPXE using:

make bin/ipxe.usb DEBUG=realtek

That should produce some output relating to the NIC initialisation, which you can post here.
