NAME

     adw -- Advansys PCI 16bit SCSI Host adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device pci
	   device scbus
	   device adw

DESCRIPTION

     This driver provides access to the 16bit SCSI bus connected to the Advanced Systems Products, Inc.  ASC3550 Ultra, and ASC38C0800 Ultra2,
     SCSI Host Adapter chips.  Both chips support, synchronous transfers (20MHz and 40MHz max respectively), 16bit transfers, tagged queueing, and
     up to 253 concurrent SCSI transactions.

     Per target configuration performed in the AdvanceWare menu, which is accessible at boot, is honored by this driver.  This includes synchro-
     nous/asynchronous transfers, maximum synchronous negotiation rate, wide transfers, disconnection, tagged queueing, and the host adapter's
     SCSI ID.  The global setting for the maximum number of tagged transactions allowed per target is not honored as the CAM SCSI system will
     automatically determine the maximum number of tags a device can receive as well as guarantee fair resource allocation among devices.

HARDWARE

     The adw driver supports SCSI controllers including:

     o	 AdvanSys ABP940UW/ABP3940UW
     o	 AdvanSys ABP950UW
     o	 AdvanSys ABP970UW
     o	 AdvanSys ABP3940U2W
     o	 AdvanSys ABP3950U2W

HISTORY

     The adw driver appeared in FreeBSD 3.0.

AUTHORS

     The adw driver was ported by Justin T. Gibbs from the Linux driver written by Bob Frey of Advanced System Products, Inc.  Many thanks to
     AdvanSys for providing the original driver under a suitable license for use in FreeBSD.

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.
