Could you be more explic= it > about what you do and don't support with the sil3114 controller? I do support the *hardware* that is the SiI3114 chip. That means you=20 will get access to the individual disks on the 4 SATA channels just like = any other (S)ATA controller. Now the RAID "stuff" you are talking about is all done in *software* so=20 it depends on the BIOS type/vendor and what type of metadata it uses.=20 Software RAID's are supported from Promise/HighPoint/LSI as I stated=20 above, if thats not what you have the ATA driver doesn't know how to=20 pick up the metadata from the disks, and therefore doesn't know what the = RAID looks like. However, atacontrol can create at RAID for you on any type of (S)ATA=20 controller, you just have to live with certain restrictions, se 'man=20 atacontrol' for details. -S=F8ren
