The aic device driver is used to drive only the SCSI controller on this card. The audio portion of the Sound Blaster 16 SCSI-2 requires a separate Solaris device driver (sbpro) for operation.
The SCSI interface on the Sound Blaster 16 SCSI-2 audio card cannot be used as a primary (boot) disk controller since it has no BIOS. The system must be booted from a disk attached to another controller.
