controller. Some testing has already been done, but its still greenish. RAID's has to be setup via the BIOS on the SuperTrak, but all RAID types are supported by the driver. The SuperTrak rebuilds failed arrays on the fly and supports spare disks etc etc... Add "device pst" to your config file to use. As usual bugsreports, suggestions etc are welcome...
