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.

      For ISA or Vesa Local Bus adapters, one kernel config 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 wildcard values are
      used, the driver will query the device for its current settings and use
      those.  If the port address is a wildcard, the driver consults an inter‐
      nal table of possible port address locations and attaches to the first
      unattached card it finds.  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 syn‐
      chronous/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.

AUTHORS

      The adv driver was ported by Justin T. Gibbs from the Linux driver writ‐
      ten by Bob Frey of Advanced System Products, Inc.  Many thanks to Advan‐
      Sys for providing the original driver under a suitable license for use in
      FreeBSD.
 

HISTORY

      The adv driver appeared in FreeBSD 3.0.
 

Sections

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
