IDe Controller Question

[Ryan]

My computer was shipped to me with the hard drive and cd-rom connected to a promise 33 controler, and not to the IDE controllers on the motherboard. Well, I needed an extra PCI alot, so i moved my HD and CD-ROM to the ide controller. It there and performance loss/gain from doing this?

anyone?

Depends on the motherboard. If it is a motherboard that is based on the BX chipset then you've got no worries. The BX chipset added cool things such as Ultra DMA which offloaded alot of the load from the memory and the CPU which results in a pretty good performance gain. My guess is that they included that controller for a good reason.

It depends on the mobo.

What motherboard did it come with.


Ultra dma33 realy is not fast compared to what is out now days.


do you notice any slow downs? That werenot there before.

Does your bios detect DMA and set the drives up to use it.

Do you have dma setup enabled in windows.



It could increase performance or decrease run a disk benchmarking utility that should tell you definately.
