Good that makes things simpler. Maybe I can find a way to disable it in the
BIOS.
I got a PCIe SATA card. Right now I'm using 1/4 of it for an optical drive,
but if I should acquire an SSD that disables an important SATA port, the
card may become more useful.

Yeah, I see myself doing a logic puzzle and losing quite a bit of hair if I
add an SSD.
