I have an Asus A7N8X-E deluxe and was wondering what's the purpose of Bios setup. Also is there a default for this? Is it just to let the OS know what hardware is installed? When starting the puter, how do you get into bios? See I never setup the bios on one before and just want to make sure it's running right and operating the way it should. What and how's the best way to do so. Believe it or not, I just built this one and somehow got it to the point that it's working fine although when it first fires up I notice it comes up Primary drive not found and secondary drive not found. But like I said,,,,it works fine.
