NAME
adv - Advansys PCI 8bit SCSI Host adapter driver

SYNOPSIS
device pci
device adv

For one or more SCSI busses:
device scbus0 at adv0

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.

ABP3960UA | 20MHz | 240
ABP970 | 10MHz | 240
ABP970U | 20MHz | 240

Multi Channel Products (Commands are per-channel):
Adapter | MaxSync | Commands | Channels
ABP950 | 10MHz | 240 | 2
ABP980 | 10MHz | 240 | 4
ABP980U | 20MHz | 240 | 4
ABP[3]980UA | 20MHz | 16 | 4

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.
