I found a problem. When I installed DSM7.0.1 on the H610 and B660 motherboards, it was prompted that SATA1234 was disabled. After analysis, I came to the conclusion that perhaps the SATA controllers of H610 and B660 were castrated from the 8 SATA of Z690 and disabled. Caused by 4 SATA, so I can't install DSM because it always has 4 non-existing SATA ports disabled, hope H610, B660 are supported
