I've always wondered why the one I have that have both was called AT - it wasn't ;-) >Yes they are, but who needs this for a DOS box. Why not just find >some older technology real cheap.

Interesting, I saw a motherboard with IDE RAID on it when I was investigating the market. But I didn't feel a need to buy more than one HD so I never looked into it.
