December 30, 201411 yr Hi all, I've just installed a shiny new Plextor PCIe M.2 2280 SSD on the M.2 mount for a ASROCK Z97 Extreme4 Mobo. The drive appears to be working : 1. The flash screen indicates it's connecting successfully via PCIe x2 2. Drive details are showing up in the MB BIOS/UEFI settings screen However it does not appear in unRAID v6b12 (existing system). Has anyone else used a M.2 slot? Is there any reason that this drive would not be showing up?
December 30, 201411 yr Author Interestingly, I've found that the drive shows up when VT-d is disabled in the BIOS. Seems like it might be related to the Marvell controller and the ID's it provides to Xen, as per this post : http://lime-technology.com/forum/index.php?topic=33511.0
