I have been able to boot a Samsung NVME 250GB SSD from a 1x PCIe adapter which I purchased from amazon.   this is how I am currently booting my Truenas box]]> Fri, 29 Mar 2024 01:34:27 +0000 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=115759&title=asrock-j5040itx-miniitx-pcie-m-2-boot#115759 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=115755&title=asrock-j5040itx-miniitx-pcie-m-2-boot#115755 Author: jcoelho

that is not true. I am currently running and booting a 250GB NVME Samsung 980 SSD from the 1x PCIE slot via a cheap Amazon adapter. The PCIe specs allows for you to run devices on less than the optimum number of PCIe lanes. There is of course a trade off since running a PCIe 4x device on a 1X lanes you lose 75% of your bandwidth. But for me the loss in performance is worth freeing up a sata port.

Also I have confirmed that adding a card to the M.2 Wifi A/E keyed slot will work with one of those 2 port Sata adapters. I have not confirmed if it will boot from those ports but it is readable.]]> Fri, 29 Mar 2024 01:32:44 +0000 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=115755&title=asrock-j5040itx-miniitx-pcie-m-2-boot#115755 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=100948&title=asrock-j5040itx-miniitx-pcie-m-2-boot#100948 Author: threadzipper1957

The PCIE slot on the board has only one PCI Express 2.0 lane, for an M.2, you must have at least 4 lanes, so it will not work.
The M.2 key E slot, is meant for Wifi cards, it cannot handle an M.2]]> Fri, 12 Aug 2022 17:06:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=100948&title=asrock-j5040itx-miniitx-pcie-m-2-boot#100948 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=100804&title=asrock-j5040itx-miniitx-pcie-m-2-boot#100804 Author: Xaltar

I would send a support ticket to ASRock and ask:

They will know for certain and what steps you need to follow if it is possible.]]> Wed, 03 Aug 2022 23:40:48 +0000 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=100804&title=asrock-j5040itx-miniitx-pcie-m-2-boot#100804 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=100802&title=asrock-j5040itx-miniitx-pcie-m-2-boot#100802 Author: Kernel32

Hi everyone,

I can't boot from M.2 SSD connected to PCI-E via an adapter. Does this motherboard support boot from PCI-E slot?]]> Tue, 02 Aug 2022 22:02:59 +0000 https://forum.asrock.com/forum_posts.asp?TID=24793&PID=100802&title=asrock-j5040itx-miniitx-pcie-m-2-boot#100802
