GDT8x00RZ, GDT8x13RZ, GDT8x14RZ, GDT8x22RZ, GDT8x23RZ, GDT8x23RZ,
GDT8x24RZ, GDT8x33RZ, GDT8x43RZ, GDT8x46RZ, GDT8x53RZ, GDT8x63RZ, and
GDT8x86RZ.
Also supported, are select Intel RAID controllers containing firmware
derived from ICP Vortex.
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
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.

The gdt driver first appeared in OpenBSD 2.7.
AUTHORS
The gdt driver was written by Niklas Hallqvist <niklas@openbsd.org>, in-
spired by the Linux driver by
Achim Luebner <achim@vortex.de>.
BUGS
An ISA 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 informa-
tion on how to do that is not public.
