 .Nd Adaptec SCSI host adapter driver
 .Sh SYNOPSIS
-.Cd controller "aha0 at isa? port" \&"IO_AHA0\&" "bio irq ? drq 5 vector ahaintr"
+.Cd controller "aha0 at isa? port ? cam irq ? drq 5"
 .Cd controller scbus0 at aha0
 .Sh DESCRIPTION
 This driver provides access to the
 .Tn SCSI
-bus connected to an Adaptec 154xA, 154xB, 154xC or 164x host
-adapter.  It also works for compatible cards like the BusLogic 545 and
-the Adaptec 174x in 154x emulation mode.
-For Adaptec 174x cards in enhanced mode the
+bus connected to an Adaptec 154xA, 154xB, 154xC, 154xCF, or 154xCP
+host adapter.  Host adapters supporting a 154X compatible interface,
+such as some Tekram controllers and the Adaptec 174x in 154x
+emulation mode can, also be attached with this driver.  For optimum
+performance, Adaptec 174x controllers should be configured in
+enhanced mode and attached via the
 .Xr ahb 4
-driver should be used instead.
+driver.
+.Pp
+One kernel config 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 wildcard, the driver consults an internal table of possible port address
+locations and attaches to the first unattached card it finds.  The possible
+port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and 
+0x134.
