Result: Very stable and reliable NVMe boot drive and system this "ancient" Asus Z87-Deluxe-Dual mobo with i7-4770K cpu sporting an Aptio 4 BIOS/UEFI; which should now run like a top on the latest Windows 10 Preview Build 18992
Use BIOS FLASHBACK method, check your manual at page 2-12.

NVMe mod to run UEFI NVMe SSDs using module NvmExpressDxe_4.ffs dated 04/18/2018 All the rest is pretty standard ROM/EFI updates.
Enjoy your new NVMe capable modded bios with MDS/Meltdown/Spectre microcode updates.
BTW microcode v 28 fixes Microarchitectural Data Sampling (or MDS) side-channel vulnerabilities in Intel CPUs in addition to Spectre/Meltdown vulnerabilties.
As usual make a back up of your current bios and drives!
Thank you. I’m a novice but through this site and the great people on here, I was successfully able to flash the BIOS, install a Windows boot drive (NVME M.2 drive plugged into PCIE slot). I had to do a fresh install of Windows, however. No biggie. Thank you again for this post and this website. NO way I could have done it without your help and excellent advice. Your efforts are greatly appreciated.
Thank you very much for the modded BIOS. I tried to flash it with "ASUS BIOS updater for New 4th Gen Intel Core Processors" an the answer has been "BIOS update fail". I tried in UEFI BIOS Utility with "ASUS EZ FLASH 2 Utility v02.00" but I had "Security verification failed". How can I do to flash this BIOS? With older methods?
Hi there. Is there any chance that this supports the Asus TPM-L 20-1 R2.0 module? I believe there’s a path to getting it there as the Asus Z87 Sabertooth has the update to it, however this board has not received that update
