Hello.

My motherboard is a Gigabyte GA-Z170XP-SLI revision 1.0. The BIOS version is F3. My operating system is Windows 10. The CPU is an Intel i5-6600. The power supply is 650 watts. The graphics card is an EVGA GTX 970. I have 8GB of RAM. I have two 1TB hard drives. I have a Blu-ray drive. I have an Intel network adapter.

I have had this computer for almost two years now with no problems.

I read that I needed to update my motherboard in order to protect against the recent problems discovered in Intel CPUs.

I read that I should use the "GIGABYTE Intel ME Critical FW Update Utility" to do this. I used version B17.1218.1 of the utility. When I ran the utility, it said, "Error 8746: Firmware update not initiated due to invalid image length." A post in the forum for my motherboard manufacturer suggested that I could upgrade the firmware manually by running FWUpdLcl64.exe with ME_11.8_Consumer_D0_H_Production.bin (these files came with the utility). I did this.

The update installed successfully. When I restarted my computer, it showed the BIOS splash screen, then the Intel Boot Agent, and then the BIOS splash screen again. After this, the computer shut off and rebooted, restarting the process. I can still enter the BIOS setup, but Windows will not start. The computer does not make any beeps.

I have tried pressing the "Load Optimized Defaults" button in the BIOS before restarting. I've tried using the "Previous Values" button in the BIOS before restarting. I've tried connecting the CLR_CMOS pins before loading the defaults and restarting. I tried starting the computer with the Windows 10 setup disc in the disc drive (I made sure the drive was first in the boot order).

I tried holding down the power button for 30 seconds while the computer was unplugged before starting the computer. I tried starting the computer with and without Intel CPU virtualization enabled. I tried using a bootable USB drive made with Rufus to run FreeDos. I tried starting the computer with the hard drives disconnected.  

None of these changed my computer's behavior.

I have NOT tried using Q-FLASH to change the firmware yet.

What, if anything, can I do to fix this?

Thank you in advance for your help.

Hi,

 

What happens exactly when you try to boot from the Windows 10 DVD?

 

What is the version of the BIOS you have?

Trying to boot from the Windows 10 DVD has no effect. After the BIOS splash screens and the Intel Boot Agent, the computer shuts off and reboots as before.

 

The BIOS version is F3. The BIOS date is 07/24/2015. The BIOS ID is 8A09AG0R. I can't find another way to refer to the BIOS.

Intel Boot Agent;

 

How do I prevent the Intel Boot Agent from executing?

  1. Enter your BIOS configuration and find the order settings for the boot devices.
  2. Move the boot agent down the list after the hard drive or the device you prefer to boot from.
  3. https://www.intel.com/content/www/us/en/support/articles/000005626/network-and-i-o/ethernet-products.html

 

You supposed to have bios version F22c, dated 12-01-2017 it has the Intel ME patch (Update Intel ME for security vulnerabilities)

http://www.gigabyte.us/Motherboard/GA-Z170XP-SLI-rev-10#support-dl

 

Windows update will provide you with the patches for the latest Intel flaws (Meltdown & Spectre)

See if you can update the BIOS using Q-FLASH

 

Version F3 is very outdated the latest version available https://www.gigabyte.com/Motherboard/GA-Z170XP-SLI-rev-10#support-dl is F22C

 

 

Edit: By the way those Intel ME updates don't have nothing to do with the recent flaws Meltdown & Spectre

You can read about the security problems related to Intel ME for example on the following links:

I used Q-FLASH to update the BIOS to version F22C. Windows now starts, and everything seems to be normal.

 

The problem seems to be solved. Thank you for your help and your quick responses.

Good. It seems Gigabyte fail to include a note that the Intel ME Critical FW Update most likely requires a specific BIOS version.

If you check, I think you'll find that all manufactures (oem and retail) will require a bios or chipset firmware  flash to fix the Intel ME flaw

On the bios download web page from Gigabyte, is is noted in the description

I don't know why they would offer the ME update on its own really.  But obviously they do.

Something to do with the firmware level, your bios is the first thing to recognize the chipset and start the boot.

I got this blurb;

 

If you are at risk, you must obtain and install firmware updates from your computer's manufacturer, if and when they become available. The new code was developed by Intel, but it needs to be cryptographically signed by individual hardware vendors in order for it to be accepted and installed by the engine.

 from here;

Its two different things the Intel ME firmware and the BIOS, that's why they are independent. The Intel ME code is provided by Intel but the features available are decided by the manufacture I guess and the hardware involved. The BIOS need to know about the ME part and in some there are options "to control the other module" most likely the reason that the BIOS must be also updated.
