(Thanks Asus, now I have reason to hate you too. Luckily this makes my setup of mentioned motherboard together with Intel i7-3770K and 32 GB DDR3 RAM less obsolete. I didn’t try that yet but based on all the feedback it seems working pretty well. Just follow this How to get full NVMe support for Intel Chipset systems from 6-Series up on how to mod and flash BIOS for your motherboard. The most amazing thing is that you actually can get full NVMe support in your BIOS. Those 'test BIOS' releases seemed to have cured the IVRS errors. Asus introduced NVMe boot support to newer lines of motherboards and (as usual) not backported it to older lines. As you can see in the link to the thread in the Xen forums, ASUS issued a 'test BIOS' to me for my ASUS M5A99FX PRO R2 (BIOS: M5A99FX-PRO-R20-ASUS-9903.CAP) and another 'test BIOS' for a Sabertooth 990FX R2 (BIOS: SABERTOOTH-990FX-R20-ASUS-9901.CAP). As these motherboards already have UEFI and we use modern operating systems (Windows 8/8.1/10), it’s all about software. However the most trivial yet most complicated thing is to get the NVMe storage in PCI-E adapter boot as system drive. The great thing about PC modularity is that even few years old PC can get USB-C or M.2 support via PCI-E adapters (that provide enough speed and power). With my less than 4 year old motherboard (Asus P8Z77-V PRO Thunderbolt), I can upgrade to few fast non-NVMe starages on PCI-E but it won’t be as fast and efficient as NVMe. No single new feature ever comes to old motherboard BIOS. Just like in the smartphone market, most motherboards usually receive few BIOS updates within one year and that’s it.
