UPDATE: I have discovered two of the problems: (1) There must be a connection from NIC1 to NIC2, as described above; (2) The video must be set to "Legacy", not "UEFI"; (3) The SATA must be set to Rapid Storage Technology enterprise "RSTe", not "ACHI". With these three changes, Windows installer gets to the point where it is asking for disk drivers. I have been unable to install the proper drivers, but this is progress.
I had a similar situation 4 years ago with S5520HCT boards .... not sure if it applies to you or not , but this is what I have in my notes:
05-13-2012: Intel S5520HCT Hangs When Installing Windows
This was the solution supplied by Intel support:
Follow the steps below to resolve the issue:
Update the system board BIOS to the latest version. Go to Intel Download Center and select product family, product line, then product name to find the correct BIOS file.
Change the BIOS setting, PCI AER Support, to Disable. before installing the operating system. Go to BIOS > Advanced > PCI Configuration.
Connect the network ports to a network, switch, or back to back (connect both ends of the network cable to different ports on the same computer) before the operating system loads the embedded NIC driver.
After the operating system install completes, download the latest Network Drivers for Windows.
This issue only affects network controllers based on the 82575 or 82576 chipset.
