The machine independent +drivers that use this code access the hardware through a +common interface. (see +.Xr scsibus 4 ) +This common interface interacts with a machine dependent interface, +such as +.Nm zssc , +which then handles the hardware specific issues. +.Pp +The +.Nm +interface handles things such as DMA and interrupts as well as +actually sending commands, negotiating synchronous or asynchronous +transfers and handling disconnect/reconnect of SCSI targets. +The hardware that +.Nm +uses is based on the NCR53c710 SCSI chip. +.Sh DIAGNOSTICS +.Bl -diag +.It zssc%s: abort %s: dstat %02x, sstat0 %02x sbcl %02x +The scsi operation %s was aborted due to error.
