38.Sh DESCRIPTION
39This driver provides access to the 16bit
40.Tn SCSI
41bus connected to the Advanced Systems Products, Inc.
42.Tn ASC3550 Ultra ,
43and
44.Tn ASC38C0800 Ultra2 ,
45SCSI Host Adapter chips.
46AdvanSys products incorporating these chips include the
47.Tn ABP[3]940UW ,
48.Tn ABP950UW ,
49.Tn ABP970UW ,
50.Tn ABP3940U2W ,
51and
52.Tn ABP3950U2W .
53Both chips support, synchronous transfers
54(20MHz and 40MHz max respectively),
5516bit transfers, tagged queueing,
56and up to 253 concurrent SCSI transactions.
57.Pp
58Per target configuration performed in the
59.Tn AdvanceWare
60menu, which is accessible at boot,
61is honored by this driver.
62This includes synchronous/asynchronous transfers,
63maximum synchronous negotiation rate, wide transfers, disconnection,
64tagged queueing, and the host adapter's SCSI ID.
65The global setting for the maximum number of tagged transactions allowed
66per target is not honored as the CAM SCSI system will automatically determine
67the maximum number of tags a device can receive as well as guarantee fair
68resource allocation among devices.
