AHA(4) BSD Kernel Interfaces Manual AHA(4)NAMEaha — 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.
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.
