.Sh NAME
|
|
.Nm ahb
|
|
.Nd Adaptec EISA SCSI host adapter driver
|
|
.Sh SYNOPSIS
|
|
.Cd controller ahb0 at isa? bio irq ? vector ahbintr
|
|
.Cd controller scbus0 at ahb0
|
|
.Sh DESCRIPTION
|
|
This driver provides access to the
|
|
.Tn SCSI
|
|
bus connected to an Adaptec
|
|
174x hostadapter in either
|
|
.Dq Em standard
|
|
or
|
|
.Dq Em enhanced
|
|
mode. If the controller
|
|
is set to standard mode (using the
|
|
.Tn EISA
|
|
configuration utility),
|
|
the driver will automatically
|
|
switch the card to enhanced mode during the device probe.
|
|
.Pp
|
|
.Sy N.B. :
|
|
When configuring a system
|
|
with both
|
|
.Xr aha 4
|
|
and
|
|
.Nm
|
|
drivers, the
|
|
.Nm
|
|
driver should be listed first in the kernel configuration file. This
|
|
ensures that the
|
|
.Nm
|
|
driver will find the Adaptec 174x boards before the
|
|
.Xr aha 4
|
|
driver probes for Adaptec 154x boards.
|
|
.Pp
|
|
Note that no I/O addresses are configured in the kernel config file. The
|
|
174x uses
|
|
.Tn EISA
|
|
slot-specific I/O which is configured automatically.

.Sh AUTHOR
|
|
The
|
|
.Nm
|
|
driver was written by Julian Elischer for
|
|
.Tn Mach
|
|
2.5. It was converted to automatic
|
|
.Tn EISA
|
|
configuration by Justin Gibbs.
|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver first appeared in the
|
|
.Tn 386BSD
|
|
patchkit.
