Bengal,
Yes.
Setup two IDE disks comming off the same ribbon cable, These will be the RAID array.
have another disk coming off the OTHER IDE channel, This will be the O/S.
If I know the Mobo you are talking about there SHOULD be another set of IDE channels that are non-RAID, Check the mobo manual or makers website.
That will do it.
As for the thread going off topic - It happens!
