     These controllers support RAID 0, RAID 1, RAID 5, JBOD, and
     superpositions of those configurations.

     Some cards support both I2O and a so-called `Mass Storage' mode of
     operation.	 This driver only supports the `Mass Storage' mode; I2O mode
     is supported by the iop(4) driver.	 However it is recommended to use
     these cards in `Mass Storage' mode.

     Although the controllers are actual RAID controllers, the driver makes
     them look just like SCSI controllers.  All RAID configuration is done
     through the controllers' BIOSes.

     The management interface is provided through the bio(4) device or one of
     the daughter sd(4) devices as implemented in the bioctl(8) utility.
     Logical disk status is exposed under the hw.sensors sysctl(8) and can be
     monitored using sensorsd(8).  For example:

	   $ sysctl hw.sensors.ami0
	   hw.sensors.ami0.drive0=online (sd0), OK
	   hw.sensors.ami0.drive1=degraded (sd1), WARNING
	   hw.sensors.ami0.drive2=failed (sd2), CRITICAL

     bio(4), intro(4), pci(4), scsi(4), sd(4), bioctl(8), sensorsd(8),

     The ami driver first appeared in OpenBSD 2.9.

     The ami driver was written by Michael Shalayeff <>.

     Management functions were implemented by Marco Peereboom
