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

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 message” in question and the primary use of the NVMe, for data storage or OS boot.

EDIT: Well the purpose of this mod is, primary its the use of the NVMe as OS boot drive and get a better performance than regular rotational hdd or sata 3/6Gbps disks
But as this is a mod, further preparations/settings must be set, so follow Fernando’s guide here, specially point#4: [HowTo] Get full NVMe support for all Systems with an AMI UEFI BIOS
This assuming that indeed the mod was applied…

- For regular storage, just go in OS disk management, just delete old partitions and format as new.

(The mod is not needed because OS knows how to work with standard NVMe disks, the mod itself is only needed for boot)

In Virtual Disk Manager when trying to format it appears the Windows Message: “The format did not complete successfully”.

I would like to use it for OS boot but if it doesn’t work properly I’d use it for data storage.

Thx.
