Hi man! My GA-Z87X-D3H rejected this bios. Is this mod bios compatible with my D3H? How can I adapt it to recognize this bios and boot nvme? Thank you for your support!

My son has had this in his computer for over a year without issue.

Use BIOS Q-Flash method, see page 89-91 of your manual.

Make sure you are using the the bios from Post #1 at the top of this thread.
BIOS is already NVMe capable, as my son is using it with the Samsung 950 PRO SSD.

Ok, i am using Q-flash. The Q-Flash show me the error message: BIOS ID CHECK ERROR. My MB model is D3H, it's the same bios as UD3H?

no you need the full GA-Z87X-UD3H

For your GA-Z87X-D3H see here:

RE: [OFFER] Gigabyte GA-Z87X-D3H updated BIOS vF9 : NVMe mod, EFI, & microcode update > 25

Hi hancor.

I had already managed to update the bios and successfully updated. I downloaded the standard bios F9 and updated with UEFITool by adding the nvme express.ffs as tutorial explains. Now I normally initialize via nvme. I just have a "problem", every time I need to restart windows, my monitor is on a black screen and no image appears. After reboot via reset button the boot starts windows normally. I do not use video card, only video onboard. I'll try to re-upgrade from bios, with the one you attached, maybe fix this. Thanks man!

Yes, I updated to the latest EFI GOP Driver Haswell 5.0.1036 ----> 5.5.1034 so hopefully that helps.

Cheers

I´ve tried the modded F11c but now I´m stuck in a bootloop with error code 32. Switching to the second bios works but of course without the possibility of booting from my nvme. Any ideas how to flash the first bios with a nvme modded bios?
[EDIT] I found a solution: Booting from backup/second bios, entered QFlash, load bios file from USB stick, used switch to main/first BIOS and flashed BIOS. Voila - F10b as main BIOS, no more bootloop error 32. Either something is wrong with the F11c version or the modding messed sthg up. Anyhow, thanks for the modded BIOS. Running OS from NVMe works like a charm.

The F11c bios was for a specific request; the preferred bios is contained in the FIRST post as F10b.

Glad you found your way of the boot loop to NVMe bliss!

Cheers

BTW microcode v 27 fixes Microarchitectural Data Sampling (or MDS) side-channel vulnerabilities in Intel CPUs in addition to Spectre/Meltdown vulnerabilties.

I guess it was too early to get all frantic. I´m still having booting issues with the latest mod, esp. from a cold boot. I switched already the PSU. Switching to unmodded backup bios works fine. Any ideas?

I did start from scratch. Re-downloaded the file, used a freshly formatted FAT32 freedos stick and flashed via efiflash. Went smooth so far. Also turned back on CSM. I´ll keep you posted.
