|
.Nd Advansys PCI 16bit SCSI Host adapter driver
|
|
.Sh SYNOPSIS
|
|
.Cd device pci
|
|
.Cd device adw
|
|
.Pp
|
|
For one or more SCSI busses:
|
|
.Cd device scbus
|
|
.Sh DESCRIPTION
|
|
This driver provides access to the 16bit
|
|
.Tn SCSI
|
|
bus connected to the Advanced Systems Products, Inc.
|
|
.Tn ASC3550 Ultra ,
|
|
and
|
|
.Tn ASC38C0800 Ultra2 ,
|
|
SCSI Host Adapter chips.
|
|
Both chips support, synchronous transfers
|
|
(20MHz and 40MHz max respectively),
|
|
16bit transfers, tagged queueing,
|
|
and up to 253 concurrent SCSI transactions.
|
|
.Pp
|
|
Per target configuration performed in the
|
|
.Tn AdvanceWare
|
|
menu, which is accessible at boot,
|
|
is honored by this driver.
|
|
This includes synchronous/asynchronous transfers,
|
|
maximum synchronous negotiation rate, wide transfers, 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.
|
|
.Sh HARDWARE
|

The
|
|
