Hi,

This my moded Bios For Asrock Z77 pro4 based on Official 1.80 FW
The mod add support for NVMe SSD on Pci-e on boot for Windows (10) installation.

I join the original BIOS too if needed :).

Hi Karnox,
I plan to "boost my configuration of my old asrock Z77 which is currently runinng on W10 on a hdd.
I initialy plan to buy a ssd (Crucial 500Go CT500MX500SSD1), but i saw that is was possible to get better result with a pci card that support an NVMe SSD.
On some forums, i read that the bios of the asrock was not able to support NVMe as a boot device. On some other, it could be possible but with a BIOS upgrade. (your files ...)
Have solve this issuer ? is you configuration is running well ? If yes, Could you please tell me wich PCI card and M2 ssd you've bought ?
Mny Thks in adv

Hi,
It works very well for me with W10 64:
Adapter PCI-e to M.2 NGFF M Key SSD NVMe
with NVMe disk as boot device:
SAMSUNG 970 EVO PLUS MZ-V7S500BW 500 GB NVMe
Bios Z77PRO41.80MOD

A big, big thank you to Karnox :)
ps.
could you (Karnox) modify the newer BIOS Z77PRO42.00?

Thank you very much Karnox!

I've flashed the mod BIOS but Windows 10 shows an error message when trying to format the M.2 disc (connected via PCIe).

Any solution??

It would be useful if users share the "Error" in question and the primary use of the NVMe, for data storage or OS boot.
