It's BIOS-level RAID under an Intel ICH chip. It's called MatrixRAID. I have no personal problem with Intel MatrixRAID. What I'm telling you is that FreeBSD's support for it is horribly, horribly broken. You *will* lose your data. Read my Wiki entries in full. I'm only going to say this once more: please reconsider. You very likely are not going to be able to recover that failed array. The last person who had this problem had to boot a Linux LiveCD and attempt to use Linux tools to repair it. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
