It's just a hardware feature, either you have it or you don't. It would be listed in your manual or on the web site for your motherboard...
The DMA setting would be in your BIOS:
Gotta enable all that. Then you have to check in Windows to see if it's really enabled (should say in device manager or something). If not, here are some things to try. Also you have to be sure your devices support DMA mode but it's rare to find some that don't.

The highest possible mode... if multi-word is the highest possible setting than set it to that, but usually it's called DMA mode 1, DMA mode 2, DMA mode 3, etc just like the various PIO modes.
The 4-in-1 drivers are here somewhere (you used to be able to directly link to the driver download, but not now, sorry) and ensure that your hardware capabilities are used since Windows does not normally come with the most up to date chipset drivers. The 4-in-1 drivers, or "Hyperion" as they are now called, are the name of VIA's chipset drivers (instead of "driver" nVidia calls it "Detonator" or "ForceWare", ATI calls them "Catalyst", etc, it's just marketing). It used to be called 4-in-1 because you'd get an AGP Gart, IDE driver, Chipset INF files, and PCI routing driver. These are all very important to install to get top performance!

Ohhh I see. I thought it was 2x max.
