" rel="nofollow - So this is my first ASRock motherboard and not really feeling it so far simply because it doesn't seem to be functioning properly; but perhaps I'm missing something and you fine ladies and gents can assist me.

Brand new build. Putting a Samsung 960 EVO M.2 NVMe SSD in for my storage. Have used this model drive on other builds and it is fantastic.

My problem is I cannot get the BIOS to recognize this drive, or any other drives for that matter. I have it plugged into the M.2 socket on the back of the mobo and it's secured. Still nothing.

I have attempted to plug in my known working SATA III HDD and it wasn't being recognized at all either. The BIOS is updated to the P4.40, so it's fully updated, so I don't know if I'm missing something or if I just have a bad board. Thoughts?

Thanks all.

Justin

justinleland, there is a Beta 4.43. Seems like it fixes many problems. Please do some research. Please post your specifications in your signature as I have. Enjoy, John.

Assuming that your issue is related to your M.2 NVMe SSD not being detected then go to https://www.asrock.com/mb/AMD/Fatal1ty%20AB350%20Gaming-ITXac/index.asp#BIOS" rel="nofollow - https://www.asrock.com/mb/AMD/Fatal1ty%20AB350%20Gaming-ITXac/index.asp#BIOS and update to the latest BIOS. P4.60 fixes that problem and also another one associated with the on-board WiFi card. Unfortunately, it doesn't contain the latest AGESA. Hopefully there will be another release soon that does.

Thanks for the post. I just found out what was wrong for me from another thread where someone mentioned the 4.6 bios.

I did need the new bios and had been trying to install it in hopes it would recognize my Adata 128 M2 drive. The USB flash drives I have I thought had all reformatted to ExFat... which is unsupported by the BIOS flasher.

After diving through all of them, I finally found one that was formatted to FAT32 and it fixed not being able to see the ADATA SU800 128g M2 SATA Drive.

It also fixed a couple other issues such as the CPU thermal sensor mis-reporting actual temps (it had been reporting 127C instead of the 39C it does now).

Ok... that's done. It posts and now to see if it's going to BSOD when I start using the on-board WiFi. *crosses fingers*

**edit**
Windows 10 will not reformat to FAT32. So yeah... that's a thing.

exfat handles the BIOS flash perfetly well, as any version of FAT will.

I haven't tried too use an exFAT formatted USB flash device for updating the BIOS. I have a collection of 8 GB and 16 GB ones I use and they all came FAT32 formatted. Yours is likely to be a 64 GB one or bigger if it defaults to ExFAT.

The WiFi issue is definitely fixed in BIOS P4.60 but there remain issues of fan control and power management that I'm hoping will be fixed soon.

It can do FAT32. Put the USB drive in, navigate to it in the file explorer, right click, select format. When the panel opens up, you can change the format type to FAT32, exFAT, NTFS, or Default, just like on windows 7. If you don't have this option, then something is corrupted in your windows 10 install.
