+Adaptec EISA SCSI host adapter driver
+.Sh SYNOPSIS
+.Cd "controller ahb0 at isa? bio irq 11 vector ahbintr
+.Cd "controller scbus0
+.sp
+For each disk:
+.Cd "device sd0
+.sp
+For each tape device:
+.Cd "device st0
+.sp
+For one or more cdroms:
+.Cd "device cd0
+.Sh DESCRIPTION
+This driver provides access to SCSI devices connected to an Adaptec 
+174x hostadapter in either Standard or Enhanced Mode. If the controller
+is set to Standard mode (by the ECU), the driver will automatically 
+switch the card to Enhanced mode during the device probe.
+.sp
+Please note that the above implies that when you are configuring a system
+with both aha and ahb drivers, the ahb driver should be listed first in the
+kernel config file. This ensures that the ahb driver will find the Adaptec 174x
+boards before the aha driver probes for Adaptec 154x boards.
+.sp
+Note that no I/O addresses are configured in the kernel config file. The
+174x uses EISA slot specific I/O which is configured automatically.

+.Sh NOTE
+The ahb driver does not support the newer Adaptec 274x boards. This
+is because Adaptec refuses to supply programming information without
+a non-disclosure agreement.
