You must not have your MB controller set to use AHCI.  You control

I strongly suggest you use AHCI if you can.  It is the linux preferred
way to talk to a SATA drive.

In my case, if I do that the disks disappear.

I would seriously file a bug and qualify it as a regression.  The core
linux ata devs are pushing AHCI as the preferred interface and working
to get it fully supported.

They dissapear from the BIOS. The bios sees no disk in the system, so there
is no grub, so there is no kernel, so there is no system. To whom do I

And finally, this is what the bios says it sees with the three interfaces in
