The built-in ICH5 == Intel MatrixRAID. 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.
