Hi, I recently bought a Z390-based Asus motherboard, and I noticed that enabling fake RAID in the BIOS made the NVMe drives invisible to Linux. After asking on the linux-raid list [1], I was directed to an old thread on linux-ide dating from 2016 [2]. If I understand correctly, the thread resolved to "This is a dirty trick, we don't want to support that, just leave the storage PCH in AHCI mode if you want to use NVMe drives". I bought this motherboard with two NVMe drives and intended to install both Linux and Windows on this machine (dual boot, I play games from time to time), with a RAID 1 array, and the only solutions left to me are either to use IMSM_NO_PLATFORM on Linux (and change the RAID mode setting in the BIOS every time I boot Windows), or to renounce the RAID setup altogether. Now, two years later, the same problem potentially impacts all motherboards embedding Intel 1xx/2xx/3xx chipsets, so I'd like to know if the consensus changed on this matter, or if this kind of setup will really never be supported. Thanks in advance. [1] https://marc.info/?t=155380846300002&r=1&w=2 [2] https://marc.info/?t=147709622400002&r=1&w=2 Regards, -- Raphaël Halimi
