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