34 .Nd Adaptec SCSI host adapter driver
36 To compile this driver into the kernel,
37 place the following lines in your
38 kernel configuration file:
39 .Bd -ragged -offset indent
44 Alternatively, to load the driver as a
45 module at boot time, place the following line in
47 .Bd -literal -offset indent
52 .Pa /boot/device.hints :
53 .Cd hint.aha.0.at="isa"
55 This driver provides access to the
57 bus connected to the Adaptec AHA-154x SCSI host adapters.
58 x is 0 for controllers without a floppy drive and 2 for controllers
61 One device hint entry for every card to be attached by the system is
63 Specific values for the port address, IRQ, and DRQ may be specified.
64 If wildcard values are used, the driver will query the device for its
65 current settings and use those.
67 is a wildcard, the driver consults an internal table of possible port address
68 locations and attaches to the first unattached card it finds.
70 port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and
75 driver supports the following SCSI host adapters:
87 DTC 3290 SCSI controller in 1542 emulation mode
89 Tekram SCSI controllers in 154x emulation mode

112 The AHA-154xA card does not support residuals on data transfers.
113 As a result, this card is no longer supported.
115 There have been some reports that the AHA-154xB does not work well
118 The AHA-154xCP is a plug and play controller.
119 However, its resources are set using the on-board BIOS and cannot be
121 Failures to attached for this card are often caused when the resources
122 set in the BIOS conflict.
