i ran the test using prime95 on my I7 6500u, couldn't reproduce the bug, they say not all the processors have the bug.
The secondary bios almost always has a function to copy onto other bios as a means of fixing a borked bios.
And I have seen no ill effects from the skylake bug myself. I have read that Intel will be releasing new microcode to mobo OEM producers so that with a new bios flash problem is resolved.
Asrock has also started to release new bios's with microcode fix from Intel. Extreme 7+ bios version 2.50 dropped yesterday with the fix.
