NAME
       adv — Advansys ISA/VL/PCI Narrow 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 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 narrow 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.

       For ISA or Vesa Local Bus adapters, one kernel hints entry is required for every card to be  attached  by
       the  system.   Specific  values  for the port address, irq and drq may be specified.  If unspecified, the
       driver will query the device for its current settings and use those.  If the port address is unspecified,
       the driver will search for it at one of the possible addresses.  Cards configured for ISA  PNP  addresses
       are  found  automatically.   The  possible  port addresses for these card are 0x110, 0x130, 0x150, 0x190,
       0x210, 0x230, 0x250, and 0x330.

       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.
