If the microcode update requires motherboard vendors to issue BIOS updates we are all doomed.
I've installed the hotfix for Windows, but when I run the PowerShell script to determine whether mitigation is active, the script tells me that it's not active, due to lack of hardware support. The script then goes on to give the recommendation to "Install BIOS/firmware update provided by your device OEM that enables hardware support for the branch target injection mitigation."
It's a 1-year-old ASUS laptop and I would be surprised if they even give a sane response to my question to their technical support (I doubt they will even know what I'm talking about).
There has been recent news about critical security issues in Intel CPUs, requiring a firmware update for all laptops and motherboards with Intel chips.
The vulnerabilities include the potential for malicious websites to read sensitive system memory, including passwords and encryption keys.
I have model XXYY-ZZZZ, do you have any information on when an update will be available, and where I can access it?
If not, can you attempt to escalate this ticket? The security issues are starting making their rounds in the news, and more information can be found at https://meltdownattack.com

I have another Gigabyte MB that I suspect is too old for BIOS updates anymore so I am really hoping that at some point these microcode updates due come through Windows and not just via BIOS updates.
