The
ataraid driver provides support for BIOS-based software RAID controllers. These are devices which have some simple support for several basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function. The BIOS support is largely just to create and recognize the array so that it may be a boot device.
The driver currently supports RAID formats from:
•
Adaptec HostRAID (found in Intel 6300ESB)
•
Via V-RAID (found in many VIA-based motherboards)
Status of the logical disk as well as the disks associated with it, can be viewed through the
bioctl(8) utility.
