NAME

      adw - Advansys PCI 16bit SCSI Host adapter driver
 

SYNOPSIS

      device pci
      device adw
 
      For one or more SCSI busses:
      device scbus
 

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 syn‐
      chronous/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 transac‐
      tions allowed per target is not honored as the CAM SCSI system will auto‐
      matically determine the maximum number of tags a device can receive as
      well as guarantee fair resource allocation among devices.
