Optiplex 790, INTEL-SA-00075 Mitigation

Hello all,

I'm looking for a way to patch the INTEL-SA-00075 vulnerability on our Optiplex 790 computers without updating to A19 BIOS, as A18 and A19 break PXE boot. 

I've gone through the steps in the INTEL_SA-00075 Detection and Mitigation Guide, but it's still showing the computers as vulnerable.

I've run the following commands:

Intel-SA-00075-console.exe -Unprovision

Intel-SA-00075-console.exe -DisableCCM

Intel-SA-00075-console.exe -DisableLMS

The output of the above commands now running them a second time to verify they took is (in same order as above):

-Unprovision error: Intel(R) AMT is already unconfigured on this system.

-DisableClientControlMode: This Intel(R) AMT device does not support Client Control mode.

-No Output

After successfully running those and rebooting, this is the output of Intel-SA-00075-console.exe -Discover:

Starting internal MicroLMS.

I have sent this issue to the Desktop L3 team for review. This could take awhile. I have not seen any workarounds from us or customers on this Forum. Until they release a new BIOS, you have to either live with PXE and without INTEL-SA-00075 fix or vice versa.
