35 .Nd Adaptec SCSI host adapter driver
37 .Cd device "aha0 at isa? port ? irq ? drq 5"
38 .Cd device scbus0 at aha0
40 This driver provides access to the
42 bus connected to an Adaptec 154xA, 154xB, 154xC, 154xCF, or 154xCP
43 host adapter. Host adapters supporting a 154X compatible interface,
44 such as some Tekram controllers and the Adaptec 174x in 154x
45 emulation mode can, also be attached with this driver. For optimum
46 performance, Adaptec 174x controllers should be configured in
47 enhanced mode and attached via the
51 One kernel config entry for every card to be attached by the system is
52 required. Specific values for the port address, irq, and drq may be
53 specified. If wildcard values are used, the driver will query the
54 device for its current settings and use those. If the port address
55 is a wildcard, the driver consults an internal table of possible port address
56 locations and attaches to the first unattached card it finds. The possible
57 port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and
