p These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.
p Some cards support both I2O and a so-called `Mass Storage' mode of operation. This driver only supports the `Mass Storage' mode; I2O mode is supported by the .Xr iop 4 driver.
p 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. .Sh SEE ALSO .Xr intro 4 , .Xr iop 4 , .Xr pci 4 , .Xr scsi 4 , .Xr sd 4 .Sh HISTORY The .Nm driver first appeared in .Ox 2.9 . .Sh AUTHORS The .Nm driver was written by .An Michael Shalayeff Aq mickey@openbsd.org .
