Windows Server 2016 Installation

Symptoms:     
During OS installation, system(s) at the windows logo appear hung or result in a blue screen.

Issue 1: WS2016 does not support x2APIC mode.
Issue 2: Older WS2016 OS builds (earlier than build version 14393.1378) do not support IOMMU.

Solution:      
  1. Boot to System BIOS (F2).
  2. Go to the Processor Settings section.
Perform Steps 3 and 4 only if the system configuration consists of 2 CPUs and 64 cores and above on each (total 128 physical cores and above). With 128 physical cores and above, Logical Processor must be kept disabled. Enabling Logical Processor enables x2APIC by default and results in a blue screen even after Windows Update.
  1. In the System's BIOS, disable the Logical Processor settings and save the settings.

  1. Reboot the System, Boot to System BIOS (F2) again, and go to Processor Settings section.
  2. In the System's BIOS, disable the x2APIC Mode setting.
  3. In the System’s BIOS, disable the IOMMU support setting. (This step can be skipped if using OS builds later than version 14393.1378 which carries the IOMMU Support).

  1. Save the settings and Reboot the system.
  2. Install WS2016 OS.
  3. Update Windows to the latest available update or make sure at minimum SSU KB4509091 and CU KB4512495  August 17, 2019 build 14393.3181 is installed.
  4. Reboot the System.
  5. Enable IOMMU support and Leave the x2APIC Mode disabled.

1 Socket Server
CPU Logical Processor x2APIC Mode IOMMU Support
64C x 1 Enabled Disabled Enabled
32C x 1 Enabled Disabled Enabled
24C x 1 Enabled Disabled Enabled
16C x 1 Enabled Disabled Enabled
8C x 1 Enabled Disabled Enabled
 
2 Socket Server

64C x 2 Disabled Disabled Enabled
32C x 2 Enabled Disabled Enabled
24C x 2 Enabled Disabled Enabled
16C x 2 Enabled Disabled Enabled
8C x 2 Enabled Disabled Enabled
 

Note 1: X2APIC always needs to be kept disabled, toggling it on results in a system hang even after installing Windows Update.
 
Note 2: To mitigate Issue 2, make sure to be at minimum CU KB4022723 June 27, 2017 (build v14393.1378) is installed during step 9 in the above solution.
