The firmware found 2 disks. Perhaps there is something wrong with efiboot boot device selection code. And unfortunately efiboot doesn't currently support selecting alternative boot devices. > >> OpenBSD/armv7 BOOTARM 0.1 > boot> > cannot open sd0a:/etc/random.seed: Device not configured > booting sd0a:/bsd: open sd0a:/bsd: Device not configured > failed(6). will try /bsd > boot> This suggests that we actually didn't find the boot device. So the problem might be that the boot device selection code in efiboot doesn't work for SATA devices.
