Yes, I saw mention of atacontrol somewhere in the handbook, the drives
all SCSI. It seems atacontrol only addresses IDE? Excuse my ignorance on
the subject of ATA vs SCSI :/

files# atacontrol list
ATA channel 0:
    Master: acd0 <CD-ROM 50X/10> ATA/ATAPI revision 0
    Slave:       no device present
ATA channel 1:
    Master:      no device present
    Slave:       no device present
