BIOS-related FAQ

Please start your PC and press the [DEL] or [F2] key while booting to enter the BIOS setup program. The BIOS version is shown in the second line on the main screen.

Just as with many modern PCs, a current Shuttle XPC does away completely with a BIOS but uses a pure UEFI firmware instead. The terms UEFI firmware and BIOS are widely used synonymously, but hardware initialising is now performed by the UEFI. Users might not even notice, but the operating system must be installed and executed in UEFI mode. UEFI creates a GUID Partition Table (GPT) on the system partition instead of a Master Boot Record (MBR). A PC running pure UEFI firmware alone must have a 64-bit operating system installed.

All settings and parameters defined in the BIOS are stored in CMOS. To delete these settings and reset CMOS, follow the instructions below.

The instructions show examples of where the button or jumper to clear your machine's CMOS is located on different models. If you can't find the button/jumper on your model, more detailed information on type and position can be found in the Quick Guide (QIG) that came with your machine.

Remove the mains plug and reset/press the jumper/button for approx. 10 seconds. You may need to use a pointed object such as a ballpoint pen to push the button. After clearing CMOS, start up the computer and load “Optimized Defaults” in BIOS, save and restart.
