Some of these chips are sometimes used in low-cost software-based RAID systems. This mode of operation is not supported in OpenBSD.
另外搜到 BSDnexus forums 有人2006年就在使用 VT6420，而上述页面里根本木有这款硬件。o Acard ATP850U, ATP860, ATP860-A, ATP865-A, ATP865-R

这种情况让我们怎么办？？pciide0 at pci0 dev 15 function 0 "VIA VT6420 SATA" rev 0x80: DMA
=====================================================
另外，OB的softraid不能在安装的时候一步到位么？手册里的例子是已经有OB的情况下再添加三块硬盘建RAID 1。有无可能在已经安装好系统的单硬盘机器上再加一块硬盘，组成 RAID 1，若可能的话，数据会自动复制么？但我看手册后猜测这是不可能…有实际经验的筒子请赐教！
