AHB(4) BSD Kernel Interfaces Manual AHB(4) NAME
ahb -- Adaptec EISA SCSI host adapter driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device scbus device ahb Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ahb_load="YES" DESCRIPTION
This driver provides access to the SCSI bus connected to an Adaptec AHA-174X host adapters in ``enhanced'' mode. Tagged queueing and syn- chronous SCSI transfers are supported. HARDWARE
The ahb driver supports the following SCSI host adapters: o Adaptec AHA-1740 o Adaptec AHA-1742 o Adaptec AHA-1740A o Adaptec AHA-1742A 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 incom- patibilities of this nature. SEE ALSO
