SCSI controllers, respectively. Once these drivers are tested on the alpha, these man pages can probably be moved up a directory to reflect the fact that they're architecture independent. An mdoc guru should probably look at the AUTHORS sections in both of these pages -- the .An macro seems to cause strange spacing problems. Reviewed by: ken Submitted by: gibbs

.Sh NAME
|
|
.Nm adw
|
|
.Nd Advansys PCI 16bit SCSI Host adapter driver
|
|
.Sh SYNOPSIS
|
|
.Cd controller pci0
|
|
.Cd controller adw0
|
|
.Pp
|
|
For one or more SCSI busses:
|
|
.Cd controller scbus0 at adw0
|
|
.Sh DESCRIPTION
|
|
This driver provides access to the 16bit
|
|
.Tn SCSI
|
|
bus connected to the Advanced Systems Products, Inc.
|
|
.Tn ASC3550
|
|
as found on the ABP940UW SCSI Host Adapter board. This chip
|
|
supports, Ultra SCSI (20MHz), 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.
