ahb -- Adaptec EISA SCSI host adapter driver
This driver provides access to the SCSI bus connected to an Adaptec
AHA-1740, AHA-1742, AHA-1740A, AHA-1742A host adapters in ``enhanced''
mode. Tagged queueing and synchronous SCSI transfers are supported.
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.
