Ok, that's what I was suspecting, as I noticed now that the VIA SataRaid
has the same problem :) Now I understand why people said that some of
these devices are not real hardware RAID, this works because it needs a
special driver. (I never understood how a hardware component could do
that, but never thought about specialized drivers)
I'm used to ServeRAID.
So whatever I configure in the BIOS, it has no effect on Linux, right ?
