As I said earlier, I have a big problem with this 2412 , but what happens is a bit long to explain, so I will try to make myself as clear as possible …if capable of it…
A fortnight ago I received a brand new equipment (LENOVO AIO with APU - graphic incorporated into processor : amdgpu – and recent technologies).
At first, I tried to install Rosa (as I wanted to keep KDE4 -I don’t like Plasma5-) and noted the SSD M2 (card-disk) was absent from the instalator.
My second HD was correctly detected.
I decided then, to test what would happen with previous OMLx4 -version 2280 - I still had in my documents.
Note well => that the SSD M2 appeared in the KDE partition program.
So, I decided to see further (launching an installation) what Calamares would say.
“NO” SSD M2 appearing in Calamares.
And this was the end of my try, I didn’t install anything.
Later on, I installed “Mint Cinnamon” without the faintest problem => on my recently formatted SSD M2 ! Start now in 6 seconds !
…But Cinnamon, is not made for me, I installed Fedora 29 and again, my SSD M2 was perfectly recognized.
To day, I launch OMLx4 version 2412 as recommended by Rugy and => No SSD M2 appearing => nor in KDE partition program, neither in Calamares.
A look into dmseg says :

I cannot guarantee my disk is perfect, I can guarantee nor Mint neither fedora dmesg have similar lines.
So I, of course, didn’t install the system; it is useless to have half of the equipment working and especially, If you cannot install things where you want.
The kernel of this 2412 is the same (4.20.4…) I have on the Fedora, why do they actuate differently ?
Why KDE partition was seeing the SSD M2 in 2280 version, and not in this 2412 ?
Why Calamares remains blind to this SSD in both versions ?
The rest of dmesg message has (afaik) no problem; everything -including IOMMU or recent technologies- is normally detected.
It has come to my mind that, maybe, the detect-system is looking for a uefi or boot partition, or again a GPT partition, while I have formatted this SSD with “bios boot partion” and start directly from MBR… I don’t know if this will help…
Sorry to bother but I think it is important for the devs, to have knowledge of this kind of annoyance with some equipments.
