what is it and is it an option in a modern BIOS?

I ask because I got an interesting message on another list othat I participate in.

[quote]Even though an AGP card may not support vdpau acceleration, a p4 should be able to use the Nvidia driver to get some openGL 2D accelerated output for XBMC. You should also have hyperthreading turned on in the BIOS, so the system will see two CPU cores, as XMBC will take advantage of that for maybe a 20% performance boost. My netbook, with a slow 1.2 GHz hyperthreaded Intel Atom CPU and 945M graphics, is still able to play back 720p h.264 encoded movies smoothly on MX 14.
