Hello ZacB, I am sorry for the inconvenience.
I included below the BIOS recovery process in case it is needed.
You may also want to try the F7 update method.
In case the issue persists you may contact your local Intel support team for assistance.
When you try from within the BIOS, just select 'No' when it prompts you to check for a new BIOS. Then it should let you point to the BIOS on the thumb drive.
I hope this helps.
Just to follow-up on this, I've alerted the BIOS engineering team, who will investigate the problem. In the meantime, Jason's steps are perfect as a workaround.
I've tried what Jason suggests already. When I attempt to manually update the BIOS using a thumbrive, I am able to select the .BIO file, then it asks if I want to upgrade the BIOS to this version (0021). I click "Yes" then it reboots, and then boots up normally into Windows.
Also, I'm unable to get into the BIOS using the F2 key. I've tried several different USB keyboards. The only way I can get there is by using the recovery options in Windows to reboot into UEFI Mode. I'm not able to get into the F7 BIOS Recovery mode at all.
I will try the BIOS recovery process that joe_intel posted and report back later.
I was able to update the BIOS by removing the jumper and booting into recovery mode. I think the jumper must have been set to locked mode. Once I replaced the jumper, I was able to press F2 to entire the BIOS.
Thanks for your help!
I just heard from the BIOS engineer, who says the auto-update feature in BIOS can fail if you're behind a corporate proxy, which explains why I so easily reproduced it. Does that apply in your case?
No, I think the problem turned out to be that the jumper on the mainboard was set to the security mode. I didn't realize this until I removed the jumper in order to try updating the BIOS using the recovery mode.
Thanks for the suggestion!
Enabling legacy boot did it for me. I'm sure there are many out there who disabled legacy boot for HDMI audio so I hope this helps.
