But the concept, and some of the software, is the same. It's pretty common in OEM deals for the actual vendor of the software/hardware to remain unknown. From what it looks like, the RAID functionality is all in software, as opposed to running on a chip embedded in the ICH5. Ken -- Kenneth Merry ken@FreeBSD.ORG
