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.

  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.
