GDT8x63RZ, and
     GDT8x86RZ.

     Some Intel RAID controllers containing firmware derived from
ICP Vortex
     are also supported.

     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.

DIAGNOSTICS    [Toc]    [Back]

     pci_mem_find: expected mem  type  00000000,  found  00000002
This message
     occurs  during  autoconfiguration if jumper J4 is set to map
the controller
     memory below 1MB in physical memory.  The  driver  primarily
wants this
     jumper  to be set the other way round, but it will work with
it in any
     setting.  If the diagnostic is considered a nuisance,  alter
jumper J4's
     setting.

HISTORY    [Toc]    [Back]

     The gdt driver first appeared in OpenBSD 2.7.

AUTHORS    [Toc]    [Back]

     The   gdt   driver   was   written   by   Niklas   Hallqvist
<[email protected]>, inspired
 by the Linux driver by
     Achim Luebner <[email protected]>.

BUGS    [Toc]    [Back]

     An ISA & EISA front-end is needed.

     The driver does not yet support transparent raw SCSI mode.

     It would be nice to configure the RAID units after boot  but
the information
 on how to do that is not public.
