NAME
       adv — Advansys ISA/VL/EISA/PCI 8bit SCSI Host adapter driver


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

             device scbus
             device adv

             For one or more EISA cards:
             device eisa

             For one or more VL/ISA cards:
             device isa

             In /boot/device.hints:
             hint.adv.0.at="isa"

             For one or more PCI cards:
             device pci


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.

             Footnotes:
             1.   This board has been shipped by HP with the 4020i CD-R drive.  The board has no BIOS so it
                  cannot control a boot device, but it can control any secondary SCSI device.
             2.   This board has been sold by Iomega as a Jaz Jet PCI adapter.
             3.   This board has been sold by SIIG as the i540 SpeedMaster.
             4.   This board has been sold by SIIG as the i542 SpeedMaster.
             5.   This board has been sold by SIIG as the Fast SCSI Pro PCI.

       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.
