NAME

     adw -- ConnectCom Solutions AdvanSys PCI Ultra Wide SCSI host adapter driver

SYNOPSIS

     adw* at pci? dev ? function ?
     scsibus* at adw?

     options FAILSAFE
     options SCSI_ADW_WDTR_DISABLE=mask
     options SCSI_ADW_SDTR_DISABLE=mask
     options SCSI_ADW_TAGQ_DISABLE=mask

DESCRIPTION

     The adw driver provides support for the ADW (AdvanSys) ABP-940UW, ASB-3940UW, ASB-3940U2W SCSI host adapters.

     The following kernel configuration options are available:

     options FAILSAFE
     Disables tagged command queuing, wide data transfers and synchronous data transfers for all SCSI devices controlled by the adw driver.  By
     default, tagged command queuing, wide data transfers and synchronous data transfers are used if the SCSI devices support them.

     The following options use a mask to specify which SCSI peripherals the option applies to.	The mask is a 16 bit bitfield value. Each bit cor-
     responds 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.

     options SCSI_ADW_WDTR_DISABLE=mask
     Disable WIDE data transfer for the peripherals specified by the mask value.

     options SCSI_ADW_SDTR_DISABLE=mask
     Disable SYNCHRONOUS data transfer for the peripherals specified by the mask value.

     options SCSI_ADW_TAGQ_DISABLE=mask
     Disable TAGGED COMMAND QUEUING for the peripherals specified by the mask value.
