um i am kinda wondering how does windows 8 bypass the BIOS startup screen ?
As from my understanding from the COMPTIA A+ books and CDs unless they changed how it works in the last 3 years the BIOS is the first thing to run then comes POST ( unless you said to skip it and/or shorten it ) then it searches the boot device in the order listed in the BIOS usually the CD/DVD drive then the Hard Drive ( unless the user changed it from default ) Once the OS loader is found it goes and hands off control to the OS loader. The OS loader is the software which loads the OS not the BIOS and with the BIOS being the first piece of firmware to run ( mainly b/c it never turns off ) how can Windows bypass the BIOS ?
What i will want to see is how to get to the BIOS to fix Boot order, CPU voltages and speed, RAM voltages and speed, etc. without having to go into Windows 8 as sometimes the OS is corrupted and cannot load even if the POST works saying all the hardware is there and recognized but mainly i just like to have a way to make sure everything is working in the right order for the boot order and be able to reset the voltages and speeds for the hardware when it is not stable enough to run any OS.
