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 FILES +.Bl -tag -width Pa -compact +.It Pa /sys/i386/isa/ahb.c +driver source +.It Pa /sys/i386/conf/GENERICAH +sample generic kernel config file for Adaptec based systems +.El +.Sh SEE ALSO +.Xr aha 4 +.Xr cd 4 +.Xr scsi 4 +.Xr sd 4 +.Xr st 4 +.Sh NOTE +The ahb driver does not support the newer Adaptec 274x boards.
