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. > Simple, right? :-D Yeah, I see myself doing a logic puzzle and losing quite a bit of hair if I add an SSD. > Most desktop motherboards have some sort of limitations/sharing like this > because there are only so many PCIe lanes from the CPU, but they vary in > how well they communicate the information.
