DESCRIPTION
     The ami driver provides support for MegaRAID family of RAID controllers.

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

     Some cards support both I2O and so called `Mass Storage' mode of opera-
     tion.  This driver only supports the `Mass Storage' mode, I2O mode is
     supported by the iop(4) driver.

     them look just like SCSI controllers.  All RAID configuration is done
     through the controllers' BIOSes.  iop(4) driver.
