Have any of you tried this yet? I found it out today, and I dont have any comfirmation if this truely works or not. I have DMA enabled to each drive except my first dropdown box in the Secondary IDE device.

So, anyone know of this trick? Any concequences?

Uh, yea!

This is no trick or secret. DMA has been around for more than 11 or 12 years now. It allows the hard drve to bypass the CPU and load data directly in to the system ram, where the CPU can access it. Before DMA all of the data from the Hard drive needed to pass through the CPU to gain access to system RAM and that caused a slowdown.

Just make sure that DMA is enabled in your system BIOS. The article that you are reading pertains to windows 9.x users and that is because Windows 95,98, and ME all ship by default with DMA disabled. If you are using Windows 2000 Professional, XP or newer then you do not need to worry about this since it is automatic. Just be sure to have all of you chipset drivers installed and up to date.

This is very old knowledge and is nothing new.
