DMA mixing

[uNCo]

OK after such good advice I have decided on an ECS K7S5A. (who can refuse at that price.)Before I buy the board I was wondering if I will have trouble combining an IBM 60GXP 40GB drive with my IDE Zip100 a Sony CDROM and a new ACER 2010A CD writer. With only 2 IDE ports and 4 devices to load, how do I get to combine the UDMA 100 HDD with a DMA33 or 66 device on the same 80 pin cable? Or does this mean a IDE PCI board or raid board?
Or am I just stupid?
BTW Is there a big performance diff between running PC SDR vs DDR on this board??
Thanks

If your going to hook all of these drives up.
You’ll be putting the Hard drive as master on the first controller.
To add the other 3 you’ll want to put the fastest device as slave on the 1st controller (dma66)
the put the other two on the 2nd controller as slave and master.

By adding the DMA 66 to the 100, doesn't that decrease the transfer rate of the 100 to 66?

Congrats on the board choice; it was mine as well http://www.PCGuide.com/ubb/biggrin.gif, yes you will notice an increase in application performance by using DDR, no if you put an UDMA 66 on the same channel as an UDMA 100 it will run at the 66 speed for compatiblity mode.

Thanks all for the advice. I'll report back once I have gathered the bits together and fired it up.(figuratively only of course - I'm not ready for overclocking!)
