NAME
aha — Adaptec SCSI host adapter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
device scbus
device aha
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
aha_load="YES"
In /boot/device.hints:
hint.aha.0.at="isa"
DESCRIPTION
This driver provides access to the SCSI bus connected to the Adaptec
AHA-154x SCSI host adapters. x is 0 for controllers without a floppy
drive and 2 for controllers that have them.
One device hint 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.
HARDWARE
The aha driver supports the following SCSI host adapters:
· Adaptec AHA-154xB
· Adaptec AHA-154xC
· Adaptec AHA-154xCF
· Adaptec AHA-154xCP
· DTC 3290 SCSI controller in 1542 emulation mode
· Tekram SCSI controllers in 154x emulation mode

AUTHORS
The aha driver was ported by M. Warner Losh from the bt driver written by
Justin T. Gibbs.
BUGS
The AHA-154xA card does not support residuals on data transfers. As a
result, this card is no longer supported.
There have been some reports that the AHA-154xB does not work well under
heavy load.
The AHA-154xCP is a plug and play controller. However, its resources are
set using the on-board BIOS and cannot be moved. Failures to attached
for this card are often caused when the resources set in the BIOS con‐
flict.
