Hello,

I wonder if it is possible to add in my bios support for an unsupported NVME.

I have a notebook Asus G531GT which originally had a NVME M.2 2280 WD_BLUE SN560 256GB and i bought a NVME M.2 2280 WD_BLACK SN850 1TB which freeze the notebook at startup, i am not even able to enter bios setup interface, simply freeze on Asus logo and only power works.

Is there any way to add support to this NVME or i should purchase a supported NVME drive?

Asus support team told that the drive is not on their supported devices and provided a list of supported devices which is incomplete, for sure there are few micron nvme ssd which works too. The following list was provided by Asus as supported devices, if you need to upgrade your NVME SSD please see the list below:
SSD P3X4 512GB M2 2280 NVME INT/SSDPEKNW512G8/002C/999CG3

Edit by Fernando: Thread moved into the "BIOS Modding Requests" Sub-Forum and thread title customized

If the bios originally had supported for NVMe, you can try Fernando NVMe mod and replace the NVMe DXE modules by his, a thought...
