Just installed windows 7 64-bit on a m17x-r1 and followed the Drivers list off this site. I did not mess with any of the BIOs drivers and the E-SATA drives wouldn't load. Volume works and I can control it from the little speaker icon in the bottom right of the screen; The volume-slider-control just above the keyboard to the left of the power button does not. It lights up when I touch it but does not adjust volume. The blue-tooth, Wifi, etc. buttons to the right of the button work, but the alienware picture-icon-thing that flashes in the upper left of the screen when you use them does not show up.
The FN key that lets you use the alienware specific alternate F1 - F12 buttons does not work. (i.e. eject, mute, Tpad, etc.)

Sounds like the OSD (on screen display) drivers are not installed. I think they need .net framework 3.5 to work as well, so make sure windows updates installed that first then try installing the OSD.

True, you might be missing the OSD, It is listed on drivers and downloads under the applications tag.
Volume control and FN key dont work
