Thanks for the suggestions. I checked the BIOS configuration and it appears that the SATA controller was set to IDE (not sure how that happened). I have now set it to AHCI, but I am seeing another error in dmesg....
ahci0 at pci0 dev 14 function 0 "NVIDIA MCP73 AHCI" rev 0xa2: irq 11, AHCI 1.1 ahci0: failed to start command DMA on port 0, disabling ahci0: failed to start command DMA on port 2, disabling scsibus0 at ahci0: 32 targets, initiator 32 Does this mean that AHCI on my m/b is not supported in OpenBSD? Any other thoughts?
