AHA(4) FreeBSD Kernel Interfaces Manual AHA(4) NAME aha -- Adaptec SCSI host adapter driver SYNOPSIS device aha0 at isa? port ? irq ? drq 5 device scbus0 at aha0 DESCRIPTION This driver provides access to the SCSI bus connected to an Adaptec 154xA, 154xB, 154xC, 154xCF, or 154xCP host adapter. Host adapters sup- porting 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 con- figured in enhanced mode and attached via the ahb(4) driver. 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 wild- card, the driver consults an internal table of possible port address locations and attaches to the first unattached card it finds. The possi- ble port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and 0x134. SEE ALSO ahb(4), ahc(4), cd(4), da(4), sa(4), scsi(4) AUTHORS The aha driver was ported by M. Warner Losh from the bt driver written by Justin T. Gibbs. FreeBSD 11.1 October 15, 1998 FreeBSD 11.1
