The ASRock Fatal1ty P67 Professional motherboard uses the new EFI (Enhanced Firmware Interface) for its BIOS. It gives it a little more flare and accessibility. Of course, you have Fatal1ty staring at you with his little smirk from every page, but after a while you really do not notice.
The OC Tweaker page is nice, but I found that the scroll wheel on the mouse did not work all the time on this page. I ended up using the arrow keys to move or clicking on the up and down buttons on the page. Still, there are more than enough controls here to keep you busy and to give you the best performance out of the hardware you have installed.
All the way at the bottom of the OC Tweaker page you will find a few slots to save your favourite configurations so you can quickly bounce back between overclocks as needed.
On the Fatal1ty the Advanced page seems to have all of the seldom used options. This is ok as it keeps the overclocking pages clean and all of the other tools centrally located for easy use.
You can tinker with everything from the Northbridge controls to the Storage Configuration.
The ASRock still has all of the monitoring you are used to as well as a nice boot sequence page.
In all the BIOS is clean and well laid out. I was not happy with the background image as I feel it makes the information hard to read at times. Still, that is something that I can overlook as it does not affect performance at all (it is just a little tacky).
