Windows 10: About emulating SCSI and Vulnerabilities mitigation fixes

I've been trying to emulate SCSI on Win10 1903 and it seems that Windows now blocks that type of thing.

After a lot of researching I found a workaround to make this possible:

Code: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "FeatureSettingsOverride"=dword:00020000 "FeatureSettingsOverrideMask"=dword:00020000[/quote]
But then I remember that this settings also controls the mitigation fixes of the CPUs.

I've been searching for the meaning/consequences of those values but I haven't found anything.

Does anyone knows what those values actually do??

Thanks in advance.

Mitigating the last "L1 terminal fault" vulnerabilities - possible or not?

I've read that, thanks.

If what you saying is true, this is a departure from how previous vulnerabilities were described, and just adds confusion. The previous way of doing it made far more sense, you could see if the necessary hardware (microcode) was there and if the mitigation
is enabled&working.

With this formulation, it suggests that the hardware is vulnerable, and that's it. Yes you applied the mitigations, but... hardware is still found to be vulnerable.

The whole reason we apply these mitigations is to patch the vulnerable hardware and achieve a non-vulnerable state. You don't want to see that you're still vulnerable with all mitigations in place.

Hi,

The post here may help explain how to interpret what "hardware is vulnerable to L1 terminal fault" means: https://support.microsoft.com/en-us...-of-get-speculationcontrolsettings-powershell

In short, this line will always report as True if the hardware is believed to be vulnerable to L1 terminal fault, even if the mitigation is enabled. The important part is the line that refers to "L1 terminal fault mitigation is enabled", which in your screenshot
reports as True. This indicates that the mitigation is enabled and that this device is protected from CVE-2018-3620.

Hope that helps,

SATA or SCSI?

mobos don't, OS does. And that's not emulation, just that Windows sorts it under a common list of SCSI/RAID controllers, RAID volumes are recognised the same way.
