Thanks @hancor , it worked on my board as well. A note for other users though: if AFUWIN fails for you for some reason, the method of using AI Suite’s EZ Update as described by @Wishbringer worked for me. (Well, I assume it did, since InSpectre now lists my device as protected).
As a separate but related question: does this modded bios support PCIe bifurcation? I couldn’t find an entry for it, but I was under the impression that PCIe bifurcation is often implemented along with NVMe support.
Thanks for your speed response Hancor, much appreciated. Unfortunately I bricked my bios, I used the method of updating through the AI Suite update that I found on this site. I tried using the ASUS Crashfree Bios 3 feature by putting the stock firmware on a USB stick but it’s not working, which is too bad as that is supposed to fix a corrupted bios. Guess I’ll be buying a new motherboard to get the nvme functionality.
Thank for the modded BIOS. NVME support works but there were several issues that took me hours to figure out and I would like to share the experience to help others. The first is that initially (at least for me) the drive would not show up in the BIOS despite the update. Formatting it in Windows and marking the volume as “active” in disk management had no effect on this behavior. Doing a fresh install of Windows 10 was impossible, it gives a warning that “the system might not support booting from the drive and to enable it in the BIOS” but it still let me continue, when it goes to reboot after copying files from the DVD/flash drive it fails to continue and gives error 0xc000000e, that Windows/system32/winload.exe is missing or contains errors. Startup repair can’t fix this error and the drive still didn’t show up in the BIOS. After hours, multiple flashes, searching for fixes, and Windows install attempts I found a method that worked. I had to install Windows 10 on a SATA drive and then clone that drive to the NVME SSD, only this resulted in being able to actually see the NVME drive as a boot device and successfully boot from it. After that everything seems good but I wish I had known what I needed to do beforehand, it would have avoided a lot of hassle. If there another easier way to do this then feel free to let me know. Also, for some reason I now have a “PATA SM:” boot option in the BIOS despite the board not having any IDE connections though really, I’m just glad that the drive and adapter I spent $73 on is working.
I have original Z87-A 2103 bios installed. Do i need bios mod form this page to make it work? If needed, how to install this mod? I downloaded “AMI AFU For Aptio 4, afuwin” but when i run > AFUWINx64.EXE Z87A_ROM.rom /GAN i get Unknown command or option : /GAN
What are tools and procedure to make it work? Thank you for helping.
