Please read the following page. http://linux-ata.org/faq-sata-raid.html BIOS RAIDs are supported via device mapper. I dunno which format the sil controller uses and whether dm supports it tho. Unless you have to use it for another OS, BIOS raids are usually worthless marketing crap. Just use software RAID (md). Thanks. -- tejun
