|
|

.Cd device scbus

.Pp
|
|
In

|
.Pa /boot/device.hints :
|

|
|
.Sh DESCRIPTION
|
|
This driver provides access to the
|
|
.Tn SCSI
|
|
bus connected to the Adaptec AHA-154x and AHA-1640 SCSI host adapters.
|
|
x is 0 for controllers without a floppy drive and 2 for controllers
|
|
that have them.
|
|
For optimum
|
|
performance, Adaptec AHA-174x controllers should be configured in
|
|
enhanced mode and attached via the
|
|
.Xr ahb 4
|
|
driver.
|
|
.Pp
|
|
One device hint entry for every card to be attached by the system is
|
|
required.
|
|
Specific values for the port address, IRQ, and DRQ may be specified.
|
|
If wildcard values are used, the driver will query the device for its
|
|
current settings and use those.
|
|
If the port address
|
|
is a wildcard, the driver consults an internal table of possible port address
|
|
locations and attaches to the first unattached card it finds.
|
|
The possible
|
|
port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and
|
|
0x134.
|
|
.Pp
|
|
The AHA-1640 is an MCA bus card.
|
|
Since the MCA bus is a self-identifying bus, no setting of hints is
|
|
required.
|
|

|

|
driver was ported by

|
|
.Sh BUGS
|
|
The AHA-154xA card does not support residuals on data transfers.
|
|
As a result, this card is no longer supported.
|
|
.Pp
|
|
There have been some reports that the AHA-154xB does not work well
|
|
under heavy load.
|
|
.Pp
|
|
The AHA-154xCP is a plug and play controller.
|
|
However, its resources are set using the on-board BIOS and cannot be
|
|
moved.
|
|
Failures to attached for this card are often caused when the resources
|
|
set in the BIOS conflict.
