The steps needed to access the computer BIOS, and if necessary reset the BIOS to the default settings, differ depending on the operating system. Follow the appropriate link below to access the computer BIOS.
NOTE: The computer BIOS is the software programming that configures the basic hardware settings of your computer during the startup process. If your computer encounters a problem and does not start up properly, the computer BIOS may not be configured as it should. Depending on the nature of the problem, some issues can be resolved by resetting the BIOS to the factory default settings. Resetting the computer BIOS does not initialize the hard disk of your computer and no stored data will be deleted.
