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.
