Unfortunately, I have discovered that the folks who keep up the Intel web sites and the engineers are not in sync. The fact that every 8 series MB BIOS in intel's line up has been updated just days before the HR CPUs release is telling me that the engineers did their part. Now we seem to be waiting for the support web site to catch up. Some AA numbers might be excluded, but again that info would be on the CPU support web page. We are just waiting.
ASROCK, who I will turn to after the 8 series has run it's course, is fully up to date and had it's CPU support pages and new BIOS downloads ready within 1 day of the HR release. As stated above, all the 8 series seem to support the HR CPUs with a BIOS update.
We will see!
