Hey that got it to work for me!! I have had problems following other how-to's. Well, the HD speed went from 3 MB to 22 MB. This is still a long way from 66. Is this normal? (I here 66 is almost unattainable) I have a motherboard and a hd that support ata 66 so I'm not sure what the differences are compared to having a seperate controller.
