     The ami driver provides support for the MegaRAID family of RAID controll-
     ers, including:

           Dell PERC2/DC, PERC3/DC, PERC3/DCL, PERC3/QC, PERC3/SC,
           Dell PERC4/DC, PERC4/SC, PERC4/Di, PERC4/Si, and CERC
           Hewlett-Packard 438, 466, and T[567]
           LSI/AMI MegaRAID
           LSI/Symbios 523 SATA

     These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superposi-
     tions of those configurations.

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

     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 ami driver first appeared in OpenBSD 2.9.


     The ami driver was written by Michael Shalayeff <mickey@openbsd.org>.
