.Sh NAME
|
|
.Nm ahb
|
|
.Nd Adaptec EISA SCSI host adapter driver
|
|
.Sh SYNOPSIS
|
|
.Cd device ahb
|
|
.Cd device scbus
|
|
.Sh DESCRIPTION
|
|
This driver provides access to the
|
|
.Tn SCSI
|
|
bus connected to an Adaptec
|
|
AHA-174X host adapters in
|
|
.Dq Em enhanced
|
|
mode.
|
|
Tagged queueing and synchronous SCSI transfers are supported.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports the following SCSI host adapters:
|
|
.Pp
|
|
.Bl -bullet -compact
|
|
.It
|
|
Adaptec AHA-1740
|
|
.It
|
|
Adaptec AHA-1742
|
|
.It
|
|
Adaptec AHA-1740A
|
|
.It
|
|
Adaptec AHA-1742A
|
|
.El
|
|
.Sh CAVEATS
|
|
The Adaptec 174X is very sensitive to SCSI bus termination and cable
|
|
length.
|
|
It may also have difficulties operating with some modern devices
|
|
that, due to their speed, expose timing problems in the controller.
|
|
There are no known mechanisms for working around device incompatibilities of
|
|
this nature.
