35 .Nd Adaptec EISA SCSI host adapter driver
38 .Cd device scbus0 at ahb0
40 This driver provides access to the
42 bus connected to an Adaptec
46 Tagged queueing and synchronous SCSI transfers are supported.
48 The Adaptec 174X is very sensitive to SCSI bus termination and cable
49 length. It may also have difficulties operating with some modern devices
50 that, due to their speed, expose timing problems in the controller. There
51 are no known mechanisms for working around device incompatibilities of
