.Dd February 3, 2000 .Dt ADW 4 .Os .Sh NAME .Nm adw .Nd ConnectCom Solutions AdvanSys PCI Ultra Wide SCSI host adapter driver .Sh SYNOPSIS .Cd "adw* at pci? dev ? function ?" .Cd "scsibus* at adw?"
p .Cd "options FAILSAFE" .Cd "options SCSI_ADW_WDTR_DISABLE=mask" .Cd "options SCSI_ADW_SDTR_DISABLE=mask" .Cd "options SCSI_ADW_TAGQ_DISABLE=mask" .Sh DESCRIPTION The .Nm driver provides support for the ADW (AdvanSys) ABP-940UW, ASB-3940UW, ASB-3940U2W .Tn SCSI host adapters.
p The following kernel configuration options are available: l -ohang t Cd options FAILSAFE Disables tagged command queuing, wide data transfers and synchronous data transfers for all .Tn SCSI devices controlled by the .Nm driver. By default, tagged command queuing, wide data transfers and synchronous data transfers are used if the .Tn SCSI devices support them.
p The following options use a .Em mask to specify which SCSI peripherals the option applies to. The .Em mask is a 16 bit bitfield value. Each bit corresponds to a peripheral ID. The LSB (bit 0) corresponds to the peripheral with ID 0. The MSB (bit 15) corresponds to the peripheral with ID 15. The following features cannot be disabled for the host adapter, which by default has ID 7. t Cd options SCSI_ADW_WDTR_DISABLE=mask Disable .Tn WIDE data transfer for the peripherals specified by the mask value. t Cd options SCSI_ADW_SDTR_DISABLE=mask Disable .Tn SYNCHRONOUS data transfer for the peripherals specified by the mask value. t Cd options SCSI_ADW_TAGQ_DISABLE=mask Disable .Tn TAGGED COMMAND QUEUING for the peripherals specified by the mask value. .El .Sh SEE ALSO .Xr cd 4 , .Xr ch 4 , .Xr intro 4 , .Xr scsi 4 , .Xr sd 4 , .Xr st 4 , .Xr uk 4 .Sh HISTORY The .Nm device driver appeared in .Nx 1.4 . .Sh AUTHORS .An Baldassare Dante Profeta .Aq dante (at] NetBSD.org .
