AHB(4) Kernel Interfaces Manual AHB(4) NAME ahb -- Adaptec EISA SCSI host adapter driver SYNOPSIS device ahb device scbus DESCRIPTION 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. 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. SEE ALSO aha(4), ahc(4), aic(4), cd(4), da(4), sa(4), scsi(4) AUTHORS The ahb driver was written by Justin T. Gibbs. FreeBSD 5.2.1 October 15, 1998 AHB(4)
