Are all 4 channels on the Abit KT7A-Raid ata100 and can I use 4 different devices all set to master?

[Mrcheap]

Here's my problem.

I have 1 x dvd-r
1 x cd-r
2 x HD


I want to achieve the best performance so I would like to have each device set as master on each of the 4 controllers (normal + Raid), is this possible and does it pose any problems? I remember something in the documentation mention not to have a cdrom on the Raid controller or something and do all 4 channels also support ata100?

Thanks for any feedback you can provide.

all channels support ata-100.
You can set one master per each device.
Even though it says not to put an atapi device on the raid controller, I had used it before.
