.Sh DESCRIPTION
This driver provides access to the

bus connected to an Adaptec 154xA, 154xB, 154xC or 164x host
adapter. It also works for compatible cards like the BusLogic 545 and
the Adaptec 174x in 154x emulation mode.
For Adaptec 174x cards in enhanced mode the

host adapter. Host adapters supporting a 154X compatible interface,
such as some Tekram controllers and the Adaptec 174x in 154x
emulation mode can, also be attached with this driver. For optimum
performance, Adaptec 174x controllers should be configured in
enhanced mode and attached via the

driver.
.Pp
One kernel config 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.

Tagged queueing and synchronous SCSI transfers are supported.
.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.
