43 This driver provides access to the
45 bus connected to the Adaptec AHA-154x and AHA-1640 SCSI host adapters.
46 x is 0 for controllers without a floppy drive and 2 for controllers

54 One device hint entry for every card to be attached by the system is
56 Specific values for the port address, IRQ, and DRQ may be specified.
57 If wildcard values are used, the driver will query the device for its
58 current settings and use those.
60 is a wildcard, the driver consults an internal table of possible port address
61 locations and attaches to the first unattached card it finds.
63 port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and
66 The AHA-1640 is an MCA bus card.
67 Since the MCA bus is a self-identifying bus, no setting of hints is

114 The AHA-154xA card does not support residuals on data transfers.
115 As a result, this card is no longer supported.
117 There have been some reports that the AHA-154xB does not work well
120 The AHA-154xCP is a plug and play controller.

123 Failures to attached for this card are often caused when the resources
