How to Access the BIOS of Your Computer

August 24th, 2012 by Admin Leave a reply »

Two of the most common functions why you might access your system’s BIOS are changing the boot order to allow a CD/USB or other device to boot before a hard drive or supplying a security password to lock your computer.

Unfortunately, the BIOS and the way we access the BIOS is far from standardized. Any of the following keyboard keys can invoke the BIOS (sometimes referred to as system setup): F1, F2, F10, F12, Del, Esc, or Ins. Once in the BIOS, you must use the keyboard to navigate the menus and change the settings. Again, this isn’t standardized either and there are at least a dozen implementations of the BIOS interface.

Here’s a list of the ways and access keys to press to access BIOS Setup Utility on variety of popular OEM computer systems, motherboard makers and major BIOS brands. Note that some BIOS or computer systems may have more than one method of accessing BIOS depending on when the BIOS is released.
