All RAID configuration is done through the controllers' BIOSes. .Sh DIAGNOSTICS .Bl -tag .It "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. .El .Sh SEE ALSO .Xr intro 4 , .Xr scsi 4 , .Xr sd 4 .Sh AUTHORS The .Nm driver was written by .An Niklas Hallqvist Aq niklas@openbsd.org , inspired by the Linux driver by .An Achim Luebner Aq achim@vortex.de . .Sh HISTORY The .Nm gdt driver first appeared in .Ox 2.7 . .Sh BUGS An ISA & EISA front-end is needed. .Pp The driver does not yet support transparent raw SCSI mode. .Pp It would be nice to configure the RAID units after boot but the information on how to do that is not public.
