NAME

     adv -- Advansys PCI 8bit SCSI Host adapter driver


SYNOPSIS

     device pci
     device adv

     For one or more SCSI busses:
     device scbus0 at adv0


DESCRIPTION

     This driver provides access to the 8bit SCSI bus connected to the
     Advanced Systems Products, Inc.  ASC900, ASC1000, ASC1090, ASC1200,
     ASC3030, ASC3050, and ASC3150 host adapter chips.  The following tables
     list the AdvanSys products using these chips, their bus attachment type,
     maximum sync rate, and the maximum number of commands that can be handled
     by the adapter concurrently.

     Per target configuration performed in the AdvanceWare menu, which is
     accessible at boot, is honored by this driver.  This includes
     synchronous/asynchronous transfers, maximum synchronous negotiation rate,
     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.
